I thought I'd get around to transcribing some more recognizable pieces of music, and this is an obvious favorite!
The only sources are old tapes and there are plenty of slightly altered versions, I think this is as close as one can get to that signature intro from our wholesome king. And besides, even if I got something slightly wrong, there are no mistakes. Just happy accidents ;)
I wish you happy transcribing, and God bless, my friends.
