Little Chrissy (occasionally addressed as Chrissy or Chris) is the lead singer and piano player for Little Chrissy and the Alphabeats. He is voiced by his namesake, Christopher Cerf, who also wrote most of the character's songs. Jim Henson usually performed the actual puppet until his death in 1990. Frank Oz puppeteered Little Chrissy in a sketch where Don Music rewrote "Yankee Doodle".
Little Chrissy and the Alphabeats first appeared on Sesame Street in 1973, performing the song "Count it Higher." Other songs by the band include "Exit," "You're Alive," "Rock 'N Roll Readers," and "Cluck Around the Clock." Little Chrissy has sometimes been backed by Big Jeffy, often filling in for the Lavender Alphabeat (both characters were voiced by Jeff Moss), in the songs "Gonna Rock You to Sleep," "I Go to School," and "Startin' Kindergarten." Chrissy and Jeffy have sung with Elmo on a few occasions, including a doo-wop version of "London Bridges."
Little Chrissy occasionally performed without the Alphabeats, in songs such as "Eight Balls of Fur," "Raise Your Hand," "The Opposite Song," and "Wet or Dry." He also can be seen in the audience of The Amazing Mumford's magic act in the storybook, The Amazing Mumford Presents the Magic Weather Show.
He also appeared on one monster song called "Frazzle" as one of the Frazzletone members. Despite the species, the character was a modified version of the early version of Harvey Monster with the accessories imported from the original Little Chrissy puppet like hair and yellow sunglasses. It optionally has blue fur, bigger nose, two squared teeth and a moving jaw.
