I noticed that someone mentioned NRBQ, which prompts me to recommend their wacky friend Chandler Travis; for more info see:

(Sorry not to make the above a link -- you can copy-and-paste it easily enough, no?)

As leader of the gone-but-not-forgotten bands Club Wow and Incredible Casuals, Chandler often provided an opening act for comedian George Carlin on many national tours. Almost every song he writes is at least a little funny, although some try to be minimally serious while others are just plain crazy. The live show by his current outfit, the Chandler Travis Philharmonic, are quite hilarious.

My current favorite CT song *title,* by the way, is "Village of the Darned," on last autumn's "Llama Rhymes" CD.
