When the infamous epic Caligula was first released back in 1979, a disco version of Caligula’s love theme — We Are One — was also released as a promotional gimmick.

This song is so over-the-top, so blatantly exploitive, so insidiously catchy, and so totally inappropriate for so many reasons that become clear after you watch the film it was written for that it simply cannot be ignored.  To me, this song represents everything that makes the Grindhouse great.

(As well, I hope whoever was playing bass got paid extra…)
