'Oh, she had a good pair of lungs on her as a baby,' says my mother, back in 1978, as Grease-mania grips Britain. Who? 'Olivia Newton-John.' What? Okaaay… How do you know? 'Well, I saw her. Her dad was a headmaster in Cambridge.'

Tantalising. And, unfortunately, pretty much all. I didn't pursue it then (big mistake) and my mother's no longer here to ask.

Olivia Newton-John was born in Cambridge in 1948 (yep, she's not an Australian, as almost everyone seems to think). It was a couple of years or so after father Prof Brin Newton-John became headmaster of Cambridgeshire High School for Boys, following illustrious wartime service in military intelligence.

My mother would have been 14 in 1948 and the city where she also lived would have been smaller than now. So she might have met this bonny baby at some point. Somehow. Somewhere.

Wonder if there's a link between that cryptic nugget of information my mum casually dropped into the conversation in 1978 and my long-time appreciation of ONJ's singing talents. (Picture my wife raising an eyebrow at this point.) Probably not. I think she'd already made an impact in 1974, when she flew the flag for the UK in the Eurovision Song Contest.

Olivia came fourth in Brighton with Long Live Love as ABBA triumphed with Waterloo. (Great year.)

That's got me thinking. For while we often bang on about Madonna reinventing herself, or Lady Gaga regenerating, ONJ had already been there, done that and printed the T-shirt. Sweet girl-next-door Eurovision hopeful to schoolgirl-turned-vamp in four years is quite some step.

By way of saying 'Happy Birthday', here's my take on the Ages of Olivia.

That Eurovision era

Olivia's career was treading water until 1973 song Let Me Be There broke into the top 10 of several US music charts and won her a Grammy award for 'best country female'.

The following year she secured fourth place for the UK in the Eurovision Song Contest with Long Live Love. (Wearing a flouncy, unflattering, turquoisey, toes-to-throat, bedspread-like gown!) Single I Honestly Love You topped a number of charts in different countries – her first number-one.

Grease's great days

Co-stars with John Travolta in film of Broadway musical Grease. Plays high school student Sandy Olsson (despite having 29th birthday during filming in 1977!) who in late 1950s meets 'greaser' Danny Zuko on holiday. Later, she moves to his school and their romance blossoms (after a few stumbles).

(By the way: Many people think they married in real life. They didn't!)

The film's a worldwide hit and spawns hugely successful songs, including You're The One That I Want, Hopelessly Devoted to You, and Summer Nights. Olivia is nominated for a Golden Globe as best actress in a musical. In the UK she gets an OBE.

The 1978 album Totally Hot gives her solo output a punchier edge, with songs such as Deeper Than the Night and the title track.

Then 1980 brings musical film Xanadu, with Gene Kelly of all people. Single Magic tops charts Stateside, while song Xanadu (with the Electric Light Orchestra) is a number one in several countries, including the UK.

Getting Physical

The girl-next-door feel from the early 1970s is buried by the double-entendres of the title track of album Physical, plus the sweaty look of the pictures. A couple of American radio stations ban it. The album goes double-platinum and breaks into top five in four countries. Single Physical tops America's Billboard Hot 100 chart for 10 weeks.

And overall

Dad and the fight against Nazis

Olivia's Cardiff-born father served with the RAF during the war. He spent a couple of years questioning captured Nazi pilots – using his language skills and knowledge of well-off German society.

He was part of the team that established the identity of Rudolf Hess in 1941. The one-time deputy führer had flown alone to Scotland in a bid to secure a peace agreement.

In 1942 Prof Brin Newton-John worked on the top-secret Ultra project at Bletchley Park, near Milton Keynes – the place that cracked the Enigma codes and gave the allies details of Nazi plans.

Olivia's maternal grandfather was Nobel Prize-winning physicist Max Born, who came from Germany to England before the Second World War to escape the rise of Nazism.
