The opening theme for S.A.C. 2nd GIG was originally "Rise" performed by Origa (written by Tim Jensen). However, 2nd GIG also used an alternate opening (and closing theme) when it was re-broadcast on terrestrial television, with "Rise" being replaced by "CHRisTmas in the SiLenT ForeSt" performed by Ilaria Graziano (written by Shanti Snyder).
