Sugar Shack was written by Keith McCormack and Faye Voss and perfored by Jimmy Gilmer & the Fireballs. Interestingly, the Fireballs, without Jimmy Gilmer, were a Tex/Mex instrumental band, similar to the Ventures, featuring George Tomsco, who was apparently an influential guitar player in that style. Tomsco also played on some posthumous Buddy Holly releases. The surf tune, Bulldog, is by the Fireballs as well as the tune Torquay. McCormack, in addition to writing tunes for Gilmer and the Fireballs, was a member of the The String-A-Longs, another Tex/Mex group, and also played guitar on some Buddy Holly releases. The String-A-Longs, Fireballs, and Buddy Holly, all recorded at Norman Petty's studio in Clovis, New Mexico.
