In her the defense, the AD was busy in the back of the room getting refreshments ready and delegating others. The music was not interrupted and it wasn't a problem I couldn't handle. I did raise my hand and make eye contact with the AD and she came running and escorted the man out of the room. Had it become more serious I definitely would have stopped the music and waited for help.

No one was hurt during the performance of the songs. I posted this mostly as a humorous anecdote, but thanks for concern and support.
