The way the animations have been produced for each song and with each venue in mind, I'm not sure whether we'll be able to swap venues for songs.
Each song is obviously listed at a venue in the songlist we've seen so far - but will we be able to, for example, play non-dreamscape tracks in alternate venues? Say, I Wanna Hold Your Hand on the Rooftop, or Paperback Writer in the Cavern Club?
Beyond that, is it even slightly possible we'll be able to play Dreamscape songs in live venues? I Am The Walrus in the Cavern?
I highly doubt we'll be able to play Dreamscape songs in live venues (would almost defeat the purpose of having the dreamscapes in the first place) but I have no idea whether we'll be able to mix venues.
