I can recall, that Mark mentioned some musical heroes in an older interview. He named: Hank Marvin of The Shadows, Elvis Presley, Lonnie Donegan and J.J. Cale. If you have also some old recordings by that mentioned artists, Mark´s musical background is clear. I think he said the following: " I started with a couple of old Lonnie Donegan records.." I have heard it on an US-Radioshow called Up Close produced by Dan Neer. I have it as a 2-CD-Set.
