Rocker band Queen's guitarist Brian May has revealed that Freddie Mercury will make some form of appearance at the 10th anniversary show of We Will Rock You, reports Digital Spy. Brian explained that he has been working with the production team for a while to create a certain kind of image of the late front man. Brian told BBC News that the "effect" will not be a hologram, and described it as "an optical illusion of sorts", in a similar vein to the recent resurrection of Tupac Shakur at the Coachella Festival. "People will come out saying, 'Did we actually see Freddie?" he said. "It's a little unfortunate they did that thing with Tupac as we've been trying to make Freddie appear on the stage for quite a while. "That technique is something we've looked at ourselves but I think probably for a show that runs eight shows a week it's not really quite practical."
