I was at a folk festival where a well-known Irish band spent a lot of time trying to get the audience to sing, clap, hoot & holler, etc., when the audience were really there to hear the superb playing and singing which the band were capable of providing. They wasted time on cheap bar-band tricks which they could have used to slip one more number into the program. I felt cheated. Perhaps the band felt that North American audiences are ignorant about Irish music, and have to be won over with tacky theatrics.
