Maybe writing about him and this song will be cathartic and the earworm will go away. I'm not sure I want it to leave just yet and miss the chance to hear it once more. Here is a link to a slightly faster version of the original, but very well done from all those years ago.
When the Cooker gets an earworm it is usually some misheard lyrics like Creedence Clearwater Revival's "There's a Bathroom on the Right", or Hendrix, "'Scuse me while I kiss this guy". Makes for some good humor.
