 Most of the album's contents had in fact been previously issued by Decca earlier in 1955 on the album "Shake, Rattle and Roll".Unlike the previous release, which was in the 10-inch format, the new album was a full 12-inch release and included additional tracks from 1955.It was also the first Haley album to make the Billboard charts, and was one of the very first album releases of the rock and roll genre to do so.
