FREDDIE MERCURY'S BACKSTAGE ORAL SEX TENT
Like many important men through history, Freddie Mercury liked a good blowjob. So much so that, according to reliable industry reports, in the early 80's he had his own special tent erected backstage for the sole purpose of satisfying his sexual needs. With a young male friend waiting under canvas, he would rush off stage before the encore to get some oral relief. Suitably refreshed, he then returned to the stage a very happy camper.
If anyone else has posted this then I'm sorry. No wonder he took to wearing looser pants during the 80's.
