Gone With The Bin!
I should mention that the last time I saw Otway, it was at Sheffield Poly in the Mandela Building (no, really!). The ceiling was low there, too, but Otway saw this as an opportunity, being as he is always up for creative new ways of hurting himself. He climbed up the PA, had a very dodgy moment (on several counts) with my lighting stand, then climbed onto the spaceframe supporting the ceiling, where he climbed out over the audience.
He had not considered three basic physical constraints:
1. Putting a microphone in front of the PA creates howlround, which, while having the side effect of drowning out Otway's vocals, is never much of a pleasurable experience (and a big Sorry! to Mr Frank Sidebottom for my attention to detail on this point; he'd been expecting a sound engineer not a lampie on the board, so the feedback he'd wanted was curtailed. That's what soundchecks are for, though...)
2. An SM58 microphone is not a radio mic. It is attached to a cable. Sometimes a very long cable, but generally the crew have not allowed enough spare length to reach the back of the hall, as this is not a requirement of most performers. Sure, it was plenty long enough for Otway to get tangled in it and fall flat on his face on the stage, but, part way through his aerial antics, he ran out of cable, which confused him.
3. Otway, bless him, is no muscle man. He has a lot of experience of climbing up things, but just as much of crashing to the floor ignominiously. When the mic cable length ran out, Otway was alerted to the fact that he was hanging upside down to a slippery piece of metal with condensation on.
The inevitable happened. Fortunately, Otway's head, survivor of Wild Willy's violence on many occasions (cf Headbutts), did not damage the floor, and, with the help of members of the audience, he made it back onto the stage in time for the end of the song, which had pretty much lost its way in the meantime.
He told me that he usually destroyed two SM58s per gig. This one was a 3.
