There is no song called "Behind Your Lies", I think you're thinking of QWERTY. QWERTY is technically not a b-side to the album, since it was a song the band wrote on a plane ride to Japan so they could play it live. They recorded it for LPU's 6th year CD, but not for the Minutes To Midnight sessions.
Behind Your Lies is just a fan-site name for QWERTY, and it wasn't a bonus on MTM; it was on the LPU 6 CD.
