From Album: "Christmas with the Chipmunks".

Alvin and the Chipmunks is an animated music group created by Ross Bagdasarian, Sr. in 1958. The group consists of three singing animated chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable sweetheart. The trio is managed by their human father and confidant, David Seville. In reality, David Seville was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label, Liberty Records: Alvin Bennett (the president), Simon Waronker (the founder and owner), and Theodore Keep (the chief engineer).

The Chipmunks act began with recordings first brought to life in Bagdasarian's 1950s novelty recordings under the name David Seville and the Chipmunks. For stage purposes, such as during an appearance on The Ed Sullivan Show, Bagdasarian lip-synched the words of "David Seville" in front of a small puppet theater, with puppets of the three Chipmunks also lip-synching. The puppets looked similar to the Chipmunk illustrations on the covers of some of the group's 45 RPM records. The characters were an unprecedented success, and the singing Chipmunks and their manager were given life in several animated cartoon shows, using redrawn, anthropomorphic chipmunks, and eventually motion pictures.

The voices of the group were all performed by Bagdasarian, who sped up the playback to create higher pitched, comical, squeaky voices. This oft-used process was also not entirely new to Bagdasarian, who had also used it for two previous novelty song projects, including "The Witch Doctor," but it was so unusual and well executed it earned the trio two Grammy Awards for engineering. Although the characters were fictional, they did release a long line of actual albums and singles, with "The Chipmunk Song" becoming a number-one hit single in the United States. Since Ross Bagdasarian, Sr.'s passing on January 16, 1972, their voices were performed by Ross Bagdasarian, Jr. and Janice Karman in all subsequent incarnations except for the 2007 CGI/live-action film adaptation, when they were voiced by Justin Long, Matthew Gray Gubler and Jesse McCartney respectively.
