The Song That Never Ends

"The Song That Never Ends" (originally, "The Song That Doesn't End") is a self-referential and infinitely iterative children's song. The song appears in the album Lamb Chop's Sing-Along, Play-Along by puppeteer Shari Lewis. It is a single verse long song, written in an infinite-loop motif in a march style, such that it naturally flows in a cyclical fashion, repeating the same verse over and over. It is still a very popular tune, typically sung during long car journeys. The song was written by writer/composer Norman Martin in 1988.

This is the song that doesn't end
Yes, it goes on and on my friend
Some people started singing it not knowing what it was
And they'll continue singing it forever just because
This is the song that doesn't end...

This is the song that never ends
It just goes on and on my friends
Some people started singing it, not knowing what it was
And they'll continue singing it forever just because
This is the song that never ends...

The most notable appearance of the song in the US was as the closing theme of Lamb Chop's Play-Along, a 1992 televised puppet show on PBS, though with slightly different lyrics and a slightly different title (known as "The Song That Doesn't End"). At the end of each episode, the puppets and children would sing several verses of the song while hostess Shari Lewis would try in vain to stop them. They would eventually leave (on her urging), even while beginning a sixth verse (which eventually fades out). Then, the puppet character Charlie Horse would return and try to get to sing the song again, but Shari successfully stops him by grabbing his mouth and persuading him to "go away." So Charlie leaves and slams the door (before Shari could even tell him not to slam the door).
