Failed Celebrity Geneology

I just wasted a small portion of my time trying to prove that radio DJ Dr.Demento is the father of the bandmembers of Hanson. This all started when I stumbled upon Dr. D's biography and was reminded that his real name is Barry Hansen. From here my mind made the quantum leap to the Hanson video "River" in which Weird Al Yankovic directed and starred. Prior to Weird Al's success with his parody of Michael Jacksons "Beat It", the only way you were likely to hear him was by listening to him live on the Dr. Demento Show. Therefore Hanson's father is Dr. Demento. I cannot find anything to confirm or deny this which is as much as a denial.
This is not the first time that all the useless trivia in my head has gotten jumbled and attempted to make false connections. In my childhood I was confused by the war comic character Sergeant York as I couldn't understand what he had to do with the two Dicks that played the two Darrins on "Bewitched". I thought Olivia Newton-John was married to Elton John (hey, what did I know then about homosexuality). Hell, just last week I was watching TVLand and became convinced that "The Brady Bunch"s Barry Willams must be the brother of "Happy Days"s Anson Williams. This was cleared up (sort of) by Barry himself at his personal website:
Happy Days started just as the Brady's were winding up our run. I visited the set several times. They are a very nice group of actors and I have done work with Anson Williams and Donny Most. Also I have done some promotional work for Nick at Nite with Gary Marshall. He is a very funny guy and I recommend his book "Wake Me When It's Funny" to any aspiring actor.
Damn the Internet!
