According to Billboard.com, when asked at a press conference about the possibility of Freddie Mercury getting the same treatment with Queen, Roger Taylor said:

"I don't think I want to. Were somebody [else] to use a hologram of Freddie, I would have no objection... It just doesn't sit too well with me. I don't want to appear with a hologram of my dear friend. It's the real one or no hologram for me. But I think it's an amazing effect when used properly � obviously in darkness." more on this story
