Having recently celebrated The King’s would-be 75th birthday, we’re pretty hot on Elvis/Sun trivia right now. Here are numbers 11-14 from the 75 things you didn’t know about Elvis:

“10. Elvis's first recording at Sun Records was self-funded in August 1953. He cut a two-sided acetate: My Happiness and That's When Your Heartaches Begin.

11. Elvis claims the record was a gift for his mother (bless). Cynics say he chose Sun Records in the hope of being discovered (far cheaper, amateur recording facilities were available nearby).

12. In 1954 Elvis auditioned for a place in gospel quartet The Songfellows. The band rejected him because "he did not demonstrate an ear for harmony at the time."

13. Sun Records boss Sam Phillips's first session with Elvis later that year spawned a cover of Arthur Crudup's That's All Right Mama. The recording was picked up by Memphis radio DJ Dewey Phillips who, following a flood of listener calls demanding to know who the singer was, played it repeatedly for two hours.

14. The following week, Sun received an unprecedented 6,000 single pre-orders. That's All Right Mama eventually went on to sell 20,000 copies.”

The rest, as they say, is history.
