The Grammy Award-winning animated trio, which has sold more than 43 million albums since 1958, plans to reissue an expanded, digitally remastered edition of its "Greatest Hits: Still Squeaky After All These Years" CD Aug. 18.
Capitol/EMI also will release a newly remastered version of the perennial holiday favorite "Christmas with the Chipmunks" that same day.
Alvin, Simon and Theodore haven't been limiting themselves to just music work, however. The fictional band also will be seen in a new big-screen adventure, "Alvin and the Chipmunks," a mix of live-action and computer-generated imagery, starting Dec. 14.
"My Name is Earl" star Jason Lee will play the chipmunks' human father and manager David Seville.
