My local clubs, I slip them in when the other singer isn"t there. Mind you, it was funny when someone visited a local club and asked me to sing a particular trad song, flattering me by saying it was my calling card song.

A bit of a bugger then as I had been going there almost every month for many years and hadn't ever sung it as a guy there played it all the time so I never did.

Far more common when you sing mainly trad is to have an idea what you will be singing then hear them all before your turn... A wry smile at a singaround but a bit of a bugger to fiddle your set when you are the guest. Although at a concert recently when opening for a well known singer, she said in the interval that she only had three trad songs in her set for that tour and I sang two of them... Whoops
