He played the parts seen as being done by Ralph Machio in "Crossroads." The movie sort of sucked. But if you can find a soundtrack album from the movie, and you like or love blues, BUY IT! It's AWESOME!!!!!
It would have been nice had they gotten the guitar duel between Ry Cooder and Steve Via from the movie onto the soundtrack, but my guess is that Steve was under contract by another publishing house, and they wouldn't allow it.

Correct on all counts. Though with age, Crossroads has grown on me as a "so-bad-it's-good" type film.
