I think that for both the band in the video, and in Disney, we have to take into account the locations and the audience ... The band is playing in a Subway station in NYC ... Anyone who has been there knows that you don't get in a commuter's way, or you are likely to get knocked down ... They are always in a race to get wherever ...
The audience in Disney is there to see people in costumes, mimes, magicians, etc. A band playing funky arrangements of jazz tunes is not going to attract them ...

The good thing is that concerts of ALL types - classical, jazz, rock - old and new -, pop, country, attract large audiences who want to listen to THAT music ...
Those of us here are more likely to stop and watch and listen, because we are musicians, and that's what we do ...
