I took this picture during my time as a sound engineer in the rock ‘n roll business. It’s a production clock, on stage at Twickenham Rugby Stadium during The Rolling Stones Bigger Bang world tour in 2007.

Notice it counts down to tenths of a second.

So why give you all this guff?

The Stones two and a half hour, 50th anniversary gig, in the O2 arena ended suddenly. The fans got ‘No Satisfaction’ as the last number was cut.

Why?

It was the dreaded curfew.

If the band had gone on playing even a few seconds after the curfew hour, The Rolling Stones Rock ‘ Roll Band Company Ltd, would have caught a hefty fine from the local council.

Now you know why rock concerts sometime finish suddenly.

Sorry about the quality of the picture, but I have a talent for buying mobile telephones with rotten cameras.
