John - I read through your 100 most recorded songs post with great interest, counted up and reckoned I still play over half of them, and quite a few I've recorded as solos on YouTube. That's a quasi-jazz background for you...

It seems to be some people over here in the UK who get hung up on the 1954 tradition, rather than our friends in the US. The borders between different styles of popular music in the US seem much more fluid, and the attitude much more relaxed.

What I say is, if the 1954 definition fits your idea of what you want to play and sing, then go to it. If it doesn't, then go to it anyway. As my great-grandmother from Kildare used to say, "Have what you will - and pay for it."
