Glen was much more than a country and western star he was a member of The Wrecking Crew, a group of session musicians who played on hundreds of tracks from Nat King Cole to being the house band for the Phil Spector wall of sound productions, the Beach Boys,Mama's and Papas and so many more. The only group of musicians that came anywhere near were the Motown studio band The Funk Brothers. Both bands were never credited on the tracks they played on and most of the musicians are no longer with us, but what a legacy they left.
