Earlier this month, we heard that Syfy is airing a movie this Friday called “Dead 7”, which features former members of the Backstreet Boys, ‘N Sync, 98 Degrees, and O-Town . . . FIGHTING ZOMBIES. Now, they’ve put out an EPIC theme song. It’s called “In the End” . . . and it features Nick Carter, A.J. McLean, and Howie D from Backstreet Boys . . . Joey Fatone and Chris Kirkpatrick of ‘N Sync . . . Jeff Timmons from 98 Degrees . . . and O-Town.
