25. Queen: September 25th, 1982
No wonder Wayne and Garth were fans. Queen frontman Freddie Mercury had recently blown out his voice in a fight with his boyfriend, but he still managed to pull off "Under Pressure" and a show-stopping "Crazy Little Thing Called Love." The band stopped touring four years later due to Mercury's failing health, leaving SNL as Queen's final U.S. performance with the legendary singer.
