This episode is adapted from the 1975 album Bert & Ernie Sing-Along. It was written by Joseph A. Bailey, who later recalled:

“The Bert & Ernie Sing-Along album just started with an idea from Jon Stone to do, well, a sing-along. I was watching a lot of the Marx Brothers in those days. So, an idea hit me to do a riff on the state room scene from A Night at the Opera. ...Since a record album is basically a radio show, I could make it as outrageous as I wanted. And then, Jon liked it so much we did a video version of it on Sesame Street. That was quite a production!^[1]”

Picture	Segment	Description
	SCENE 1	We open on Bert, singing the "Sesame Street Theme" while taking a peaceful bath. Ernie overhears him singing, and decides to host a sing-along in the bathroom. He drags the piano into the bathroom and starts playing, but Bert insists "I Refuse to Sing Along."
	SCENE 1 cont'd	Despite Bert's protests, more people start showing up for the sing-along: David brings his guitar, Gordon brings his bass fiddle, and Bob and Maria bring themselves. They all sing "John Jacob Jingleheimer Smith."
	SCENE 1 cont'd	As Bert repeatedly asks for a towel, Big Bird enters with a glockenspiel and he sings "Cheer Up" as the others join in.
	SCENE 1 cont'd	The Count enters, counting the people in the bathroom, as well as the tiles. They ask him for a song, and he entertains with "Bats in My Belfry", until he is shoved into the shower.
	SCENE 1 cont'd	Grover enters with a banjo, and leads everyone in "On Top of Old Smokey."
	SCENE 1 cont'd	David leads everyone (including the viewer) in "Stand Up and Pinch Your Nose."
	SCENE 1 cont'd	Big Bird feels unable to participate since he doesn't wear clothes. Bob sings a guessing game song: "I'm Going Somewhere."
	SCENE 1 cont'd	Gordon wonders, "What's the Name of That Song?" and soon, so do the others. Near the end, Mr. Hooper arrives and asks the question one last time. The Count peers out, and claims he knows the name of that song: "One million and one bats hanging in the belfry."
	SCENE 1 cont'd	The cast enters into a reprise of "What's the Name of That Song?" as Bert finally joins in with a rendition of "Sing." Everyone joins him, including Snuffy whose snuffle appears from behind the shower curtain (which, naturally, only Big Bird notices).

Notes[]

• This episode has the entire street plot play as one continuous segment (save for scene 2) before various inserts play, a precursor to the standard street scene format of the show used since season 33.
• The marching band music during the final scene is re-used from a 1971 Ernie and Bert sketch.
