On Friday evening I watched a documentary about Pink Floyd that demonstrated how central the pyrotechnics, flying pigs and sound-and-light spectaculars were to the all-round experience of seeing them live.

So perhaps I should have been prepared for disappointment when I watched tribute band Think Floyd at the pavilion theatre.

Not that there was any disappointment with the quality of the performance by bassist and vocalist Lewis Hall, guitarist and vocalist Richard Morse, Drummer Steve Farmer and keyboard player Robert Gerrard.

They were exceptional, producing brilliant versions of so many of Pink Floyd's notoriously complex songs, including the epics Shine on You Crazy Diamond and Echoes.

They threw in songs from every era of Pink Floyd's career, spanning five decades and going back to my favourite time, when they were led by the genius Syd Barrett.

The second half of the show featured a precise, start-to-finish performance of the iconic album Dark Side of the Moon.

But I was left feeling a little bit flat - not helped by an audience that seemed largely content to be spectators of rather than partakers in the show.

Capturing the essence of Pink Floyd is a complex combination of sensational sound and mind-blowing vision.

Think Floyd had the first to a tee. But they will always struggle to pull off the second at smaller venues, which inevitably dilute the experience.
