I'm a huge Beatle fan, but not in the parks.... for creative projects I could imagine it working great for background music to corresponding themes...Like I totally imagine Main Street when I hear "Penny Lane".
N-O. No. And I truly, deeply, madly love the Beatles. But I really do not like music from 'elsewhere' when I'm inside the park. It takes me from there and puts me somewhere else and brings in memories and all that.
I've heard cover bands at TT, and I heard a good one at the little stage in the UK section of Epcot. That's more than enough, thank you.
I also don't want Radio Disney broadcast at the park, or the 'songs' of Disney properties like Hannah Montana or the Jonas Brothers. I like Disneyland to be apart from the real world, tyvm.
You can tune the control pannels/music players inside Innoventions to play the Beatles. I always do this when I'm in there. I dim the lights and turn up the Beatles. You'd be surprised at the extra kick in people's steps you see when it happens.
So while yes, while I agree the Beatles wouldn't work technically as an attraction or something similar in DL, over there, it does.
