A novelty band from Vancouver, Canada, Canned Hamm is made up of two members - Big Hamm and Little Hamm. They seem to have formed sometime in early 2001, primarily as a support act for Neil Hamburger.
As of March 2001, they have put out one album - Karazma!, which is somewhat funny.
One hopes that they are intentionally not funny, or else it'd be pretty sad.
