Welcome to Muppet Wiki!
"Dancin' all the day, doin' what you do! Ain't no other letter that dances like you! WHOO!"
"Disco D" was performed on Sesame Street in the late 1970s by a trio of polyester-clad, afro-wearing Anything Muppets. The lead singer (a fat blue Muppet) praises the letter D for its dancing and the words that starts with D.
The song appears in Episode 1186.
