"My Bed Is A Boat" may be Barry Hansen's very first recording, but I'm not sure. This is a recording of him reading the title poem here, made when he was about seven years of age. He played it a couple times or so near his birthday.

"Let's All Get Demented", by Ivor Biggin, found on the 1994 Demento Society CD

"Dr. D", by The Utensils, found on the "Worse Than Slime" CD

"Astrology Rap", by Dr. Demento, found on the "Worse Than Slime No. 1" CD

"Dr. Demento" jingle by The Persuasions, from an old KPPC broadcast.

Art Schaak has the story:

I don't know if you are a Persuasions fan or not (I am), but if you look at the Capitol recordings, credit is given to Les Carter. Les Carter was the program director at KPPC, as well as whatever his involvement with the Persuasions was. He got the Persuasions to do jingles for each of the KPPC jocks. The Persuasions tape that you mentioned, which is absolutely beautiful, is that jingle for Dr. Demento.

There are some tapes that Dr. D. used to play around this time of year to celebrate his birthday. One is him reciting a poem. There is another of him playing piano, if I remember correctly. There is also something that he worked on as producer for John Fahey, if my memory serves. None of which is particularly demented.
