Do you know this song? chorus goes something like "come on, Get it on, Get it on"???

I'm pretty sure it's Bang a gong, get it on by T.Rex. T. Rex are amazing by the way. It's not Marvin Gaye, he did lets get it on and that's a slow soul song. It goes "bang a gong, get it on, get it on. I just read about the guitar part at the beginning, I'm totally right. Trust me on this one. 100 percent
