Just in time to trim the tree, the reators of the Fox musical series have released the holiday single "Last Christmas" on iTunes.
The cast, led by Lea Michele, performs the song, which was originally recorded by the pop group Wham! The single, it should be noted, is not scheduled to appear in the Dec. 9 season finale of "Glee." The series will return April 13, 2010.
"Last Christmas" is a bonus track that is being issued separately from "Glee: The Music Volume 2," which is scheduled to drop Dec. 8. "Glee: The Music Volume 1" is now in stores.
