I've been reading through this thread with increasing unease. So, after decades of singing - and every now and then pondering over the problems of accent (particularly the 'mid-atlantic variety)- I've finally decided to sing everything in my own accent. No more sounding like a demented Ramblin' Jack Elliot for me! I was born in Surbiton and so shall stick to a Surbitonian accent - whatever that may be.... and I think it would probably be best to stick to English songs too.
