Here's a nice short bio of guitarist Tommy Allsup, who played lead guitar with Buddy Holly, was an A&R man and producer for Liberty Records, and produced Bob Wills's final album. Allsup, recently inducted into the Oklahoma Music Hall of Fame, is carrying on the western swing tradition with Bob Wills' Texas Playboys.
Tommy's going to be touring Greece and the UK this June with Kevin Montgomery. You can find his MySpace page here.
