"Get It On" or "Bang a Gong" is a song by T. Rex In England, this was called "Get It On (Bang A Gong)." The title was changed on the American release so it would be less offensive. This is about sex, but most of the imagery is vague enough that many people did not pick up on it. This is a great example of "Glam Rock." There was nothing all that distinctive about Glam music, but it was characterized by the outrageous, often effeminate costumes the performers wore and the very theatrical stage shows. The band released this a year after they shortened their name. They had been Tyrannosaurus Rex.
