Little  Jerry and the Monotones are a group of hippies who sing rock and roll  tunes, usually in the style of 1950's do-wop. Many of their early songs  are about different emotions, such as "Mad," "Proud," and "Sad."
THE MONOTONES AND THEIR PERFORMERS
Each  member of Little Jerry and the Monotones is named after their primary  performer, though at times members of the group have different  performers/voices (most notably in a season two sketch in which the  group assists Grover in spelling the word “walk”, in which Jerry Nelson  performed Big Jeffy, Fran Brill performed Little Jerry, and Caroll  Spinney performed Chrissy and Rockin’ Richard), sometimes with certain  members having different voices and even being referred to by the wrong  name (for example, in “Mountain of Love”, the orange member refers to  himself as Big Jeffy, when Big Jeffy is actually the fat blue one).  Chrissy and Rockin’ Richard don’t get many solo lines in songs and often  lip-sync to the wrong voices the most, making it difficult to determine  which one is supposed to be Chrissy and which one is supposed to be  Richard.Big Jeffy  and Chrissy are only voiced by their performers, who were songwriters  for Sesame Street and not puppeteers. In a 2009 ToughPigs interview  with Jerry Nelson, he said that the group was Jeff Moss’s creation,  stating that Moss just liked doing the bass voice.

Most of the group's appearances were musical performances, and all known musical performances are listed above. However, their best-known performance is probably "Telephone Rock," in which Little Jerry sings to an annoyed operator while inside the telephone booth, getting joined by the rest of the group inside the telephone booth. By the end of the song the operator shows up with a cop, who closes the door on them and carries the telephone booth, as the band keeps singing as if nothing happens.
Two of  their few non-music appearances are sketches with Grover. In one such  sketch, they hold up the letters that spell “walk”, and once Grover says  what it spells, they walk over Grover. In another, Grover talks about  the word “exit”, as they go through the door Grover is standing in front  of in the wrong direction, once again walking over Grover.
