Rock Around the Clock was an afterthought

Today's Morning Edition music is from 60 years ago tomorrow, when Bill Haley and His Comets went into a studio in New York to record "Thirteen Women (and only one man in town)" which was released as the A-side of their first single for Decca Records.  As time was running out at the end of that session, they recorded the B-side of the single.  That song would become the 1950s anthem of youth rebellion.
