I agree with UD about pleasing the audience/employer (such as wedding receptions). Our group has played the tunes cited above countless times, smiling all the way! Once on a gig, our bass player flatly refused to play Leroy Brown. Years later, he called me long distance from a gig he was playing and asked me to quote him the lyrics to Leroy Brown over the phone! He was working a big society gig where they had to have that tune. By this time his views about particular styles of music had changed dramatically, since that was his fulltime livelihood.
