In fairness, the organisers wouldn't have expected this. Not at a gig aimed at middle-aged people, set in the palatial grounds of the Old Royal Naval College.

But then it happened, a tide of insatiable passion edging towards the stage, wrong-footing the relaxed security. A faint glimmer of fear in the eyes of the band.

It all started so well. The never-ending intro for Shine On You Crazy Diamond was perfect. Time - apt for its surroundings - followed brilliantly and the female vocals on Great Gig In The Sky had the crowd in awe.

Money and Hey You were both spectacular renditions of incredible songs.
