He and Groucho Marx were good friends. Groucho said his show was the best since Vaudeville.
He was also pals with Milton Berle.
He did a Halloween show with the Muppets that was pretty cool too.
I had one of his Christian rock albums- it was pretty good. Have a.ways liked his stuff. Lots of great stuff. He certainly lived a wild life for awhile, but got it together and now is a pretty powerful witness to,the “rich and famous” apparently.
