This is one for the amateurs (like myself).

Have you got one particular song/tune that you always bring out when it's your first time at a strange club/singaround/etc? And do you ever sing it any other time?

Me, I sang the Bonny Bunch of Roses at the big singaround on Saturday in Saddleworth. I realised afterwards that I've sung that song in more places than any other - and that I've hardly ever sung it for a second time anywhere (by choice, I hasten to add!) Have other people got a "calling card" number like this?
