Queen rockers Brian May and ROGER TAYLOR will mark what would have been the 60th birthday of late frontman Freddie Mercury on Tuesday (05SEP06). The pair will perform live at a charity party performance of London musical WE WILL ROCK YOU, which will have an "outrageous" dress theme. Mercury's mother and sister will be in the audience at the Dominium Theatre. His former personal assistant PETER FREESTONE says, "Freddie loved a party. So much so that he would often arrange one and then think of an excuse for having it."
