I have only 3 videos:
The Flea and River Phoenix one: Entertaining!
Billy Sheehan's Bass Secrets w/ Wolf Marshall: Informative!!!
John Myung Progressive Bass Concepts: Zzzzzzzzzzzzz... *snort* Huh?
Of the three, if I lost them I think I'd go out and get another copy of the Billy Sheehan vid. John Myung's might be more helpful if I were trying to play a 6, but it is too much of a headache for me to make the transition from watching/hearing his tape and applying it to my 4 string.
I actually have lost the Flea one. I hope it turns up.
