Inspired by Terry Manning's comment about perhaps needing a gun in a session, I offer up the following for your approval and amusement:
Long ago, in a land far, far away, I was working on a session with a metal band. The band was being financed by a friend of theirs who had lost a leg in a vehicular mishap. Everyone knew this except for my colleague. One afternoon as the session is rolling along nicely, the band's sponsor is wrapping the grip on a rather large hunting knife while my colleague is sitting behind the desk making small talk with him. Suddenly, the sponsor says, "Hey Randy, check this out," and stabs himself hard in the thigh of the prosthetic leg. As the knife oscillated back and forth, he laughed and laughed. My colleague almost had a heart attack.
Cheers,
Alan Tomlinson
