The Alphabet Album is by far my favorite Sesame Street album, and I was disappointed that in my youth I didn't see a lot of the songs from it performed on the show, mainly because at that point they were 20 years old. In recent years I learned an interesting fact about the album - it was originally recorded for audio purposes alone and not from existing songs on the show, and the songs were later lip-synched with puppets rather than being performed live (even our beloved C is for Cookie). With the advent of online videos I have seen a couple more of the ones I missed, but there are still many that I haven't seen. I know some of them were possibly never even filmed, but I know there are some sketches that have been shown only a few times and it's possible that even the die-hard Sesame Street community has missed them. This is what I have compiled so far: The following songs/sketches I know were filmed for the show and I have personally seen: C is for Cookie Dee Dee Dee *What's My Letter? Two G Sounds Stand Up Straight and Tall J Friends La La La Mmm Monster Meal Would You Like to Buy an O? *My Favorite Letter The Question Song Sammy the Snake *The National Association of W Lovers X Marks the Spot The Zizzy Zoomers (a * means that I never saw the sketch/song on the show in my youth, but only saw recently) The following songs, according to Muppet Wiki, were filmed and shown on the show, but I have not seen them and have found no other record of their existance: The Sound of the Letter A Just Because The following sketch I have found some other record of its existance in video form, but have not personally seen it: The R Machine The rest I have found no record or evidence whatsoever of their existance in video form: Oscar's B Sandwich Four Furry Friends Ha Ha Herbert's Silly Poem The Noodle Story The Tale of Tom Tattertall Tuttletut U Lecture A Very Very Special Letter If anyone has any information on, or even the videos of, the ones I have not seen, any help would be greatly appreciated! Thanks!
