Jack has played guitar for Jimmy Buffet, Delbert McClinton, Jimmy Hall, the Allman Brothers and many others. In addition to his guitar licks, Jack contributed several cowritten songs to Jimmy's 1996 recording "Rendezvous With The Blues", a must have for your collection.

In 1993 Jack received a phone call from friend Warren Haynes, a member of The Allman Brothers Band (ABB), who asked Jack to sub for Dickey Betts during a tour. ABB was Jack's favorite band when he was young and now it would pay off that he had learned both Duane's and Dickey's parts from all of their recordings because there was no time to rehearse. Jack flew to Dallas, Texas where he and Warren met in a hotel room to work out the harmonies and the next night he hit the stage with The Allman Brothers Band before a crowd of 20,000.
