The one were Pukas and the one based on Andy Dursin (who was Bert to Pukas' Ernie) were going through a bunch of albums trying to determine where James Horner had borrowed a piece from... And there was one "Candy" (I think that was his name) tricked Pukas into thinking Jerry Goldsmith had written to him.
I first saw some Pukas strips in Mark G. So's mid-1990s "The Horner Letter." Later it ran in FSM print magazines in the 2000s. I especially like the saga of Pukas and Candy seeing the new Jerry Goldsmith-scored Johnny Appleseed II: Deadly Harvest in the movie theater. It almost makes me wish there really was a Goldsmith-scored Appleseed franchise! (You can read it yourself: Go to the Print Backissues listed above under the "FSM Online" bar, go to Vol. 8 No. 7 -August 2003. It starts from there.)
