The bulk of the recordings on this compilation were not originally released by Sun Records during its existence and several first appeared on this album. Ken Cook's duet with Roy Orbison was originally issued on Phillips International in 1958 credited to Ken Cook. Thinkin' Tonight Of My Blue Eyes saw it's first release on this album, as did Ray Harris' Love Dumb Baby. The only song recorded on Sun containing the word "Rockabilly" was Hayden Thompson's Rockabilly Gal. Andy Anderson's Johnny Valentine and Tough, Tough, Tough saw their first release on this album and have since become iconic Sun recordings. Jimmy Wages did not have any of his Sun recordings issued until 1975. Heartbreakin' Love and Take Me were previously unissued, but their popularity was sufficient to bring Wages over to Britain to appear live. Tommy Ruick was another who never saw a release on Sun Records and his three sides on this album represent 75% of his Sun recordings. Narvel Felts, in common with a number of Sun artists, made the big time after leaving Sun, in his case in 1973. His recordings for the Memphis label remained unissued for some 20 odd years. Vintage photos of the artists and Ding Dong's detailed sleeve notes adorn the album.
