We had played Treat at the middle of the set, and during the break a couple (looked to be about my age) approached me and complimented me on how well we had covered it. They went on to tell me the story of how they came to be a couple. They were in their high school drama class together. They knew each other but only as classmates. One of the assignments each student had to do was to choose any instrumental song and pantomime a story with it, using the song to help tell the story. They both (unknown to each other) picked Treat. The rest is a great fairy tale story, he worked up the nerve to ask her out, she accepted, they fell in love and were married three years later. They went on to say they've always liked Carlos' music but Treat has always been "Their song".
THAT'S one of the reasons I love playing music, and I'll keep playing in the tribute band as long as I can if the rewards are this cool.
