The Irrational Games website has details on the soundtrack for BioShock Infinite, which includes a song sung by the game's protagonists (take that Freeman!), saying "Gary Schyman, the original composer for previous BioShock titles, has returned to the composer’s chair once again for BioShock Infinite." They offer this video of Troy Baker (voice of Booker DeWitt) and Courtnee Draper (voice of Elizabeth) in the studio recording Will The Circle Be Unbroken, hoping to inspire purchases of one of the special editions  that includes the soundtrack, or at least a visit to a revival meeting.
