There was a very special treat for those present at the second of the two knockout shows Roger Waters and his band played at London's Earls Court - Nick Mason took part!

With his custom painted kit wheeled on stage during the intermission, it didn't take long for the crowd to start to realise what was going to take place...

Without wishing to give anything away (there'll be full details on the show page itself) suffice it to say that Nick shared the stage with Graham Broad (both performing throughout) for the whole of the second half of the show, plus the encore. More pics and full details shortly!
