One of the longer running jobs I had was in a strolling duet that played for a dinner banquet portion of a recurring murder mystery weekend--the plot involved Russian royalty, and my partner was a great balalaika player and singer and knew nearly everything in the standard Russian repertoire. However, most tables asked us to play either "Somewhere My Love" or "Those Were the Days", or both. One night I counted, and we did SML 12 times.
