1) The Beatles' Sgt Pepper's Lonely Hearts Club Band is released

When this album was released in May 1967, it spent 27 weeks at the top spot and reportedly over 30 million copies have sold worldwide since then. It remains one of the best-selling studio albums in UK chart history. So it won't come as a surprise that this album was back at number one last month during its anniversary year.

2) Jimi Hendrix at Panhandle Park

Guitar legend Jimi Hendrix performed a free concert in the Panhandle Park in San Francisco in June of 1967. Crowds journeyed from far and wide to listen to music, protest against the Vietnam War and take drugs.

3) The anthem of the Sumer of Love

Written by John Phillips of the group The Mamas & Papas, San Francisco (Be Sure to Wear Flowers in Your Hair), sung by Scott McKenzie, was an instant hit when it was released in May.

But by July, it had topped the charts and stayed put for four consecutive weeks.

Produced by Phillips and Lou Adler, this track became the unofficial anthem of the summer, which the pair used to help promote the Monterey International Pop Music Festival held in June of the same year.

4) The first pop festival is held in California

Simon and Garfunkel, Ravi Shankar, The Who, Otis Redding, the Grateful Dead, The Mamas and The Papas and Jimi Hendrix, among others.

5) Barbra Streisand performs in Central Park

It's hard to believe that this American singer-actress is 75. But a key moment in her career occurred during 1967 when Barbra Streisand recorded her album, A Happening live in concert in Central Park, New York, for free in front of an audience of 135,000 people. It peaked at number 30 in the US charts and has sold over 500,000 copies.

Some of us may remember when rock stars Mick Jagger and Keith Richards appeared at Chichester Court in June 1967. Jagger was charged with possession of amphetamines, whereas Richards was charged with allowing his house to be used for the smoking of cannabis resin.

7) Jimi Hendrix plays with The Monkees

In summer of 1967, The Jimi Hendrix Experience joined The Monkees for a number of their concerts, which was quite surprising at the time, given the artist's completely different styles and sounds.

Hendrix joined the band on their first date in Jacksonville and continued to play with them for another six shows, but left the tour in July.

However, not long after Hendrix decided to leave, his tracks, Purple Haze and Are You Experienced went up in the charts.

9) Stunt man Evel Knievel

Legendary motorcycle stuntman Evel Knievel created a name for himself at this time for his mighty jumps and his remarkable recoveries.

In May 1976, Knievel successfully cleared sixteen cars in Gardena, California, but when he attempted the same jump on July 28, 1967, in Graham, Washington, he experienced a serious crash, unfortunately landing his cycle on the last vehicle. He was thrown from his bike and suffered a serious concussion.

But never one to let people down, he was back to his antics just a month later and returned to Graham on August 18 to finish the stunt.

10) Decriminalisation of homosexuality

Fifty years have passed since the decriminalisation of the homosexuality in the UK, a law which helped pave the way in gaining the equality that the LGBT community somewhat has today.

Eastern Daily Press:

Back then, the law decriminalised homosexuality with the age of the consent set at 21, but it wasn't until 94 that the age was reduced to 18. It was another six years before it was lowered to 16 in 2000.

11) In the Heat of the Night

In this intense detective thriller, based on John Ball's 1965 novel of the same name, Virgil Tibbs, a black police detective from Philadelphia becomes involved in a murder investigation in the little town of Sparta, Mississippi during a hot summer.

The film was pretty controversial at the time with its non-white lead acting role played by Sidney Poitier and it couldn't be filmed in the Deep South.

Nevertheless, it managed to be nominated for seven Academy Awards and won five in 1968.

12) Pink Floyd release The Piper at the Gates of Dawn

In August of the Summer of Love, rock band Pink Floyd released their debut studio album, The Piper at The Gates of Dawn, which was made under founding member Syd Barrett's leadership.

14) The Beatles' All You Need Is Love goes to number one

17) Race riots in Detroit

The events of the race riots in Detroit in 1967 saw a violent disturbance which broke out in early hours of Sunday, July 23.

It's thought the trouble was sparked after a police raid of an unlicensed, after-hours bar, with the trouble lasting five days.

To end the disturbance, the Michigan Army National Guard was called and President Lyndon B Johnson also requested both the 82nd and 101st Airborne Divisions.

The riots resulted in 43 dead, 1,000 people injured and over 7,200 arrests, as well as more than 2,000 buildings destroyed.

18) Aretha Franklin releases R-E-S-P-E-C-T

Although 1967 saw widespread unrest during the race riots, soul queen Aretha Franklin released her much-loved album I Never Loved a Man the Way I Love You, which contained a cover of Otis Redding's Respect.

However, Aretha transformed the song, giving it a feminist and civil rights edge. She also added the version R-E-S-P-E-C-T to the chorus, as well as the backup singers' refrain 'sock it to me'.

19) Ode to Billie Joe

Written and recorded by American singer-songwriter Bobbie Gentry, this 1967 track was an instant hit when it was released in July. It also went on to become a big international seller.

Bobbi penned the song for Billie Joe McAllister, who is said to have tragically jumped off a bridge.

20) You Only Live Twice

Towards the end of the Summer of Love, The Doors appeared on The Ed Sullivan Show and performed Light My Fire where the line 'girl we couldn't get much higher' was reportedly requested to be changed, but Jim Morrison decided to perform it the original way, which resulted in The Doors being banned from the show.
