"Alfabetmars" (sometimes spaced as "Alfabet Mars") is a song from the Sesamstraat album Bert en Ernie Vervelen Zich Nooit... Literally translated as "Alphabet March," Bert, Ernie, Grover, and Kermit sing the song while marching around and making noise. On the album's cover (reusing the photo from Bert and Ernie Sing-Along), the sheet music for "Alfabet Mars" is on the piano and in Bert's hand. The song has been included in several "Best Of" Sesamstraat albums.
