Donnie’s new TV series on HLN, Very Scary People, premiered on March 17 with two episodes about John Wayne Gacy; this week, the series featured the story of Charles Manson. Donnie talked about it on Dr. Oz, sharing chilling details.

We know Charles Manson wanted a music career, but we what we didn’t know is that he was close with Denis Wilson (Beach Boys) and that Denis turned to Neil Diamond to help Manson; Neil – thinking Charles was a good musician – eventually tried to get him a record deal. As Donnie mentions, “We make jokes about it now, all these years later, ‘Oh, Charles Manson tried to make a record;’ he really did and he almost got a record deal; he didn’t, and that’s one of the things that set him off on his murder spring.”

Check out a clip of the interview, and two previews of tonight’s episodes.
