Elvis Presley was allegedly unimpressed with his holiday song "Blue Christmas" when he recorded the song.

One of the backing vocalists on the track, Millie Kirkham, broke the news during a recent interview for the Country Music Hall of Fame and Museum.

Kirkham, who provided the backing "woos" on the track, opened up on the session and says that both the King and his producers were positive that their record label would kill the track before it was ever released.

She recalls Elvis coming into the studio and saying "let's just get this over with" and then commenting "That's one record the record company will never release."

The sessions took place in 1957 and went on to become Presley's most beloved holiday track.
