No, he was playing some goodness knows what, uke, type thing. It looked like a GCSE project.
He hardly touched it really and Dave was doing most of the singing. I really can't understand why he was there/needed. I am not even sure it was plugged in.
He did give a resounded "oh yeaah" at the end though. Implying, yes, that was truly amazing, wasn't it!? Very grungy.
