His third marriage to Margo Anderson lasted from 1964 to 1976. The couple shares a son named Kennedy.
“So then I met this girl and that was a really exciting relationship, which lasted 12 years, and out of it we had a son,” Kenny told the Independent. “In fact, the first nine years were as good as it gets, and it was only the last few that got ugly. I was touring a lot and that is part of what killed the marriage.”
