We make sure we have a varied set list (all covers) to cover all eventualities these days. However, a few years ago we played at a British Legion locally, and although being booked as a blues/rock band, after 3 songs the duty manager said some of the 'older' punters were moaning etc, saying we weren't the right sort of entertainment. We turned down a bit and played a few tunes slightly less rock/bluesy and things calmed a bit - then, some children in the club, including a couple with Downs syndrome asked to come up and sing, to which we obliged and made them part of band for a few numbers. The 'older' punters attitudes totally changed towards us and we suddenly were the greatest band they'd ever had. Funny how things work out
