Woody the Woodchuck
From Rocklopedia Fakebandica
Alvin and the Chipmunks knock-off from the album Woody the Woodchuck Christmas Sing Song (Premier Albums, Inc., XM/S 6). It's so lame, they even unapologetically cover the Chipmunks' "Chipmunk Song." That dates this after 1958, when the original came out. It's probably from 1959-1960, based on the low album number. Also, XMS stands for Xmas!
Woody's pals are Milty and Chuck, presumably also woodchucks.
Not to be confused with the very later, very Christian Woody Woodchuck, who released a 1976 album.
