April 30, 1957 - Elvis Presley recorded the classic "Jailhouse Rock". (Note: Some websites report that Presley recorded the song "Jailhouse Rock" on April 30 and May 3, and some say that he recorded it in three sessions--2 on April 30 and May 3 at Radio Recorders and 1 at MGM Studios in Hollywood, California. Presley did record songs for the movie 'Jailhouse Rock' on those other two days, but according to the book 'Elvis Presley: A Life In Music' by Ernst Jorgensen, Presley completed recording of the song "Jailhouse Rock" on April 30 at Radio Recorders.)
