Sorry to break this to everyone, but John and George are dead! A freakshow featuring holograms would not reunite The Beatles. I don't like holograms of live people who couldn't make it, so you can imagine my view of pretending the dead are living... Especially when it could never be a "live" performance, but at best a mimed performance with some tightly scripted live performance on top.
Holograms? No thank you!
