For Scottish, I also endorse Eric Bogle's warped sense of humor. Ed Miller, a Scot living in Austin, Texas, has done a number of comic songs in his extensive repertoire. His Lowlander album has an Adam McNaughton song "Cholesterol" and one about the nuttiness that can happen "At the Games" (Highland games) by George McGregor.

David Jones with Tom Goslin have a wonderful album of Brit. Music hall comedy songs called Songs of Exquisite Taste that includes such gems as "Body in the Bag" and "Right Said Fred" For other British humor, check out the parodies written by Les Barker and performed by a cadre of incredible musicians (Like Martin Carthy doing "Hard Cheeses of Old England" )

For Irish comedy, Robbie O'Connell (the Clancy nephew) has a whole album: Humorous Songs - Live with some of the very funny songs he's written himself: "Sister Josephine" and "You're not Irish"

Both the Jones and O'Connell albums have versions of " The Sick Note/Dear Boss/Why Paddy's not at work today."

Should you go even farther astray from Scotland, have a gander at the work of Lou & Peter Berryman - there are enough crazywittywildlycomic songs there to suit anyone. While some of 'em are very American, and not a few specifically Wisconsin oriented, their output is ENORMOUS & their "A chat with your mother" (F-word song) was once the most requested song at SingOut magazine.

There's many a fine recitation good for comedy, particularly ones with audience participation choruses.

Now it's time to do the hard part - learning the material
