 The Batman musical featured in Out of the Past is a nod to an actual  planned Batman musical which was to feature music and lyrics written  by Jim Steinman, of Bat out of Hell fame. The musical was announced  in 1998, but cancelled in 2005. Some of the songs written by  Steinman for the intended Batman musical, "In the Land of the Pig,  the Butcher is King" and "Cry to Heaven" were later sung by Meat  Loaf, a regular collaborator with Jim Steinman, on the album Bat out  of Hell 3.
