In what could charitably be termed an unusual PR move, Dr. Conrad Murray, Michael Jackson's former personal physician, sang a song to CNN's Anderson Cooper during a telephone interview Tuesday.

Murray, who is currently serving a five year sentence on manslaughter charges stemming from Jackson's death, introduced the song by saying, "You know what describes me? Let me sing something for you."

He then launched into a falsetto-laced version of Nat King Cole's "The Little Boy that Santa Claus Forgot," which included the lyrics, "In the street he envies all those lucky boys, but goodness knows he didn't want a lot. I'm so sorry for that laddie who hasn't got a daddy, the little boy that Santa Claus forgot."

Cooper remained stony-faced through much of the rendition before cutting his eyes from side to side ever so slightly, looking around as if wondering if he has found himself in the middle of a very strange dream.

"That song tells my story," Murray insisted. "That's how I grew up."
