A similar thing happened to me Jim in Sterling Scotland,I played a few tunes on my concertina that went well and then decided to do a very cleverly written monologue called The Old Castle written early 1900.
Half way through a drunk shouted out "Stop the talking and play yer F... Sqeezbox" I was followed by a Scot who told a monologue I could not understand a word of, but as everyone was laughing so I guessed it was funnier than my one. Not one of my best evenings.
