I just started to read a comedy thriller by Peter Guttridge called The once and future con and was struck by the opening sentences:
" When the crumhorn player fell out of the minstrels' gallery... the lute player and the bloke who'd been blowing up a furry animal's bottom..grabbed their clleague as he toppled headfirst over the carved balustrade"

It goes on to explain, disappointedly, that the instrument in question was an utriculus , a bagpipe made from the head of a goat or sheep.
I kid you not.
