P.S. What looks like the second verse in the DT version of "Jeelie Piece" is in fact the chorus, usually sung after each of the other verses.
"Cholesterol" is in the DT, but no results on a search for "Erchie Cathcairt" (or even Archie!) I have the lyrics somewhere: will post tomorrow.
And one that Adam sings, though not one that he wrote, is Shel Silverstein's "Still Gonna Die".
