The orchestra I’m in used to do an annual Halloween concert. I’d wear motorcycle black leathers and chains and go as a Hell’s Angel With A Harp. (Yes, with practice, you can pedal in heavy boots.)
Well, the Hell’s Angels I’ve known around here never wore full-face helmets; just beanie or German army-style helmets. Anyway, I didn’t want anything that would bang against the harp or cut off my view of the conductor, so I wore a leather bandana.
