Yes, Paul Burleson was the guy who played for Johnny Burnette and he was amazing. Eddie Cochran was also a great guitartist and did not receive his due for the guitar technician that he was.

As for the gentleman who claims to have played guitar for Vincent, I'd need his name and the years he claims to have played for him to verify it. But unless he wants his name spread all over the place, that probably wouldn't be a good idea.
