Link 1 - Homespun tapes. Not expensive - and very good!
And on the subject of instructional stuff. On the Savoy site, Marc is selling volume 2 of his DVD, but not volume 1. I do have an old VHS tape I got quite a few years back of his with Tracey Schwarz, which is a tutor tape - is that Volume 1?
I'm curious, Le Piquant. I've seen you play on YouTube with Sheryl Cormier's band (in front of an audience at the Liberty Theatre, no less), and you look like you're WAY past needing a beginner's instructional tape.
