FYI...I've known JA, been his friend for 30+ yrs. and can tell you for fact that he NEVER studied Bobby (who I also know). John had always been into Chet and Les and Wes and all the GREATS of that genre as well as other genres. They are both around the same age. Fact is that Bobby's brother Russell played in one of John's bands in the 80's (Hearts on Fire) where JA played in a style remeniscent of James Burton / Albert Lee. JA has been gigging in The Boston scene since '76 and has gone through several style shifts. To say JA "studied" Keyes is an insult to John's talent and obvious ability.He also studied another local player, Bobby Keyes, who had that chord-melody thing DOWN a long time before it ever occurred to JA to work on it, pretty intensely. Johnny kinda went his own way with it, and he's a much better self-promoter than BK, but I'll tell ya the folks around here (southern NH/northern MA) know Bobby Keyes is the real player in the house where that sorta "pop guitar" (in the Chet Atkins/Les Paul sense) is concerned.
BTW, did y'all know he (JA) once auditioned for Bruford, around the time Allan Holdsworth bailed?
PS: BTW..John auditioned for Bruford in London around '74ish just after Bruford left Crimson BEFORE he played with Holldsworth or Ray Gomez. Prior to John forming The Streets.
