I apologise if this has already been metioned (I haven't been here in a while), but in a recent interview with Franz Ferdinand members Robert Hardy and Nick McCarthy, they spoke about Queen:

When speaking of the lack of visual and interactive element of bands today, they said:
McCarthy: "We try to make the whole concept(performing) a happening instead of an event"
Hardy: "Yes. All the best pop bands, the great quitar bands you know like the Beatles and Queen or whatever, they just went out with their guitars and danced."
