Boy do I love this forum ! Just when you get jaded, a thread like this comes along.I first heard "Ella Speed" by Ian and Sylvia, and, like Rick says, it made the hair stand up on the back of my neck.
What I find really interesting is the link to "Bully of the Town" which is a real favorite of mine - now I'm going to have to break out the guitar and look at those chord structures more closely.
Great work - bravo !
