I've been out of touch for a few weeks but have just read through this thread - fascinating - I didn't know all this consideration took place about tradition and Englishness and all of the other items that have been discussed. I'm starting to feel guilty. I just sing songs if I like them and I think that I can sing them. Most of them end up sounding northern but that's how I speak. I'd better go off and find out more in case I'm doing it wrong!
