Since there's so much love for Bruce here.
I watched Ricky Warwick's tech do that gag with Thin Lizzy and completely lunch it. he even put special white gloves on in preparation, then completely failed to check the momentum and the butt of the guitar slammed into his tuning table and knocked all his shit on the floor. big dink in the guitar too.
We all laughed like drains tho cos the guy had been a real dick to us locals on the load in
