Dr Conrad Murray stunned viewers of Anderson Cooper's CNN show by calling in live from jail - and performing a song.
Murray was sentenced to four years in prison for involuntary manslaughter following Michael Jackson's death, and has now been called upon to testify in a new lawsuit being brought against AEG Live promoters by the Jackson family.
However, Murray has refused to testify and called into CNN yesterday - on the same day that jury selection for the case began - in order to give an interview and protest his innocence.
Speaking to Anderson Cooper, he said, "If I testify, I will testify very honestly. It is a sad thing when I look at what's going on on the television because if Michael was alive today he would be absolutely upset, he would be so unhappy with what is happening."
He then compared his upbringing to Michael Jackson's, and began singing Nat King Cole track 'The Little Boy That Santa Claus Forgot'. After the bizarre rendition, Murray said, "That song tells my story. That's how I grew up - I had no Christmases, I had no toys. I had nothing."

He then went on to claim his innocence, continuing, "I'm an innocent man, Anderson. I maintain that innocence. I must tell you, I'm extremely sorry that Michael has passed. It's a tremendous loss for me, it's a burden I've been carrying for the longest while and it's a burden I will carry for an indefinite period of time.
"The loss is just overwhelming. He was very close to me, I was close to him, we were absolutely great friends."
If Murray serves his entire sentence, he will be released on 28 October 2013.
