Theatre gig, years ago....
Original material. Quiet, attentive audience.
During a solo, our frontman / acoustic guitarist decides to relax a bit and lean against the wall at the side of the stage.
Only... it wasn't a wall: It was a curtain, masking a four-foot drop onto various bits of technical kit hidden in the inky blackness of the wings.
He barely missed a strum, despite the bruising and the broken ribs.
