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. while zappa toured europe, he learned of this version's success, and decided to create his own edited version once he returned to the united states, and released it as a single. the version released as a single contains some of the album version of "don't eat the yellow snow", most of "nanook rubs it", and the intro to "st. alfonzo's pancake breakfast." the single also appears on frank zappa's best-of, "strictly commercial", which title is taken from the lyrics of the song "nanook rubs it".
