"The Chipmunk Song (Christmas Don't Be Late)" is a novelty Christmas song written by Ross Bagdasarian, Sr. (a.k.a. David Seville) in 1958. Although it was written and sung by Bagdasarian (in the form of a high-pitched chipmunk voice), the singing credits are given to The Chipmunks, a fictitious singing group consisting of three chipmunks by the names of Alvin, Simon and Theodore. The song won three Grammy Awards in 1958: Best Comedy Performance, Best Children's Recording, and Best Engineered Record (non-classical).
