I mean the version you sing that you say you learned from us. You do not have our blessing, whether it remains in your repertoire or not. I was brought up to believe it was nice manners to ask someone if you happen upon them if it was alright to sing a song learned from their repertoire, especially if you then use it to promote yourself. That's a good old English custom you don't seem to be picking up, you've had access to me and therefore mine for well over a year now and you haven't mentioned it. That's just rude.
