I was listening to XM and they played Blues Traveler "Hook", which like many BT songs, features the incomparable harpoon playing of John Popper.
This caused me to pick up the bag o' harps and try to hang, which is impossible. So I went instead to youtube and found a series of harp lessons by Popper. Once exhausted, I saw a Richard Thompson link and ultimately found a duet of Nancy Griffith with Thompson on what is (IMO) Thompson's finest song, "Wall of Death".
Perhaps you motorcyclists out there are familiar with what the WOD is; if not, you should be.
