One of my heroes, Magic Dick of the J. Geils Band (and more recently of Bluestime), was nice enough to spend some time chatting on the phone and answering my many pesky questions about his classic blues harp instrumental, "Whammer Jammer."  I've posted an excerpt of that conversation on YouTube under the title "Magic Dick explains 'Whammer Jammer.'"  Here's the complete conversation--a free mp3 download.  (Running time 49:03)
