buddy holly recorded a phone call he made to decca in an effort to regain his rights to songs he had recorded for decca (including "that'll be the day"). he was not happy with the production that decca made and was released from his contract. decca, however, told him he could not record any new versions of songs he'd made for decca, in case they wanted to release them. this call was made to decca in an effort to convince them to let him record them since decca was not doing anything with them. at the time he made this call, buddy had already re-recorded the songs intent to release them, which he did.
