Actor Allusion: In one episode, Dave exclaims "I made that record once!" in regards to "Witch Doctor". This is because Ross Bagdasarian didn't consider "Witch Doctor" not technically being a Chipmunks song, the first true song by the Chipmunk Trio being "The Chipmunk Song (Christmas Don't Be Late)".
Keep Circulating the Tapes: There's never been a complete compilation tape/DVD or box set containing all the episodes. There exists only the aforementioned Sing Along tapes (which just have some of the musical segments) and a DVD called "The Very First Alvin Show" (which only contains one of the first episodes, along with the specials A Chipmunk Reunion and Rockin' Through the Decades).
