I never thought of the instrument as anything but a bassoon and always used that term when singing it Some American who was familiar with Bob Burns famous homemade "instrument" that he called a bazooka may have misinterpreted it and subsituted an imaginary instrument called a bazoon. More likely it was jus a confusion of spelling with the z being used instead of an s. "Puffs", instead of "pumps" makes more sense: Thanks, Mike. The only question I have about the lyrics given above is the reference to "Hennessey Tennessee." I've never known of an Irishman named Tennessee. I had learned it as Hennessey Kennessey, which sounded more Irish to me. I can't argue with the grandson of the author, though!
