^ I was thinking that when I read it yesterday...
Years ago, I don't remember sh1t like that happening. You'd end up losing leads, straps, etc... or even gaining them sometimes... but that was because we were all hopeless disorganised nurks. I even recall a keyboard player losing a mini-moog, pinched by some passer-by when he thought leaving it unattended in the back of the van, with the doors open, during the get out, was a good idea...
But a musician walking off with another musician's instrument... that's pretty sick :(
