Billy Sheehan, that is! Here's a link to a website containing an interview and several "instructional" videos you can watch. Each is several minutes long, and while it's not exactly like having a private lesson with Billy, I thought they were interesting. If you have a high speed connection, you can see them in excellent quality. I'm still trying to find his instructional videos to buy - I think they're out of print - but at least you can see his phenomenal technique and coordination on these videos. http://www.guitar.com/features/viewfeature.asp?featureID=254#LESSON The video links are down toward the bottom of the page.
