I just heard through the grapevine that a new album is coming out in December that is a collaboration between Leon Russell and Elton John. I just can't see it myself, but maybe it will make some music worth listening to. I guess there have been much stranger combinations, but I can't think of any right off hand.
But then, I like gin and margarita mix and named the cocktail I made up a Maggie Thatcher. So what do I know?
