"Saint Alfonzo's Pancake Breakfast" contains Zappa's percussionist Ruth Underwood on marimba, who added a very distinct sound to many of his songs in the early 1970s.

According to the lyrics, this scene is destined to take the place of "The Mud Shark" (a song from the live album Fillmore East – June 1971) in Zappa mythology.

[citation needed] From this point forward, the suite almost completely abandons the previous storyline (the fur trapper's blindness is never explicitly healed though an outtake of Nanook Rubs It reveals that there is a cure to his afflicted eye.

)[6] In this song a man attending St. Alfonzo's Pancake Breakfast engages in such appalling deportment as stealing margarine pats from the tables, urinating on the bingo cards, and instigating an affair with an attractive married female churchgoer whose husband is in the Marine Corps and who is into sadomasochism.

The lyrics somewhat ambiguously describe his recent sexual encounter involving a leprechaun and a sock, after which the Father proclaims that St. Alfonzo would be proud of his achievement.

The piece itself was written during Zappa's recovery from injuries suffered in December 1971, when he was pushed from the stage at London's Rainbow Theatre by a deranged fan.

Sometime after that tour, Zappa decided to drop the lyrics and play it strictly as an instrumental; eventually finding its way into the Yellow Snow suite.

[8] A disc jockey in Pittsburgh edited the album versions of "Don't Eat the Yellow Snow" and "Nanook Rubs It" to play on his radio show.
