Patti Russo appeared as Killer Queen in the Las Vegas production of Queen and Ben Elton’s musical We Will Rock You – a role for which Brian May himself suggested her. She stayed with the cast from the production’s opening in September 2004 until it closed in November 2005.
Unfortunately there is no recording available of the Las Vegas cast, but here’s a high-quality video of Patti as Killer Queen singing Fat Bottomed Girls.
