For the Elvin Bishop hit "Fooled Around and Fell in Love," it was Szymczyk who suggested the inclusion of the song on Bishop's "Struttin' My Stuff" album, feeling the blues-oriented album lacked a pop single. The song would go on to become Bishop's biggest hit. Such a pattern was repeated throughout his career. The Eagles brought him in to refine and improve their "rock" sound, and all of their biggest selling albums and songs were Szymczyk-produced. Martin Turner of Wishbone Ash has called him "my all time favourite producer". While the two did not always get along during recording, usually over Turner's bass-playing style, Turner does credit Szymczyk with giving the band a more commercial sound on one of their most successful albums, 1974's "There's the Rub".
