Just found this great interview with with Bruce and Delbert. Delbert talks about how he went from playing 1st to 2nd position on "Hey Baby", his harmonica influences, how his playing affected John Lennon on Love Me Do, and going to Liverpool and "bumping" the Beatles. Interesting that Lennon calls a diatonic a blues harp and a chromatic a harmonica. Worth a watch for sure!
At 2:30 Delbert explaing all you gotta do to learn harmonica...lol
I had seen this interview before but cant remember where but I must admit that "just figuring it out" has been a lot more difficult for me than it was with delbert
