Maybe a showing of Beatles HARD DAYS NIGHT or HELP is a more fair comparison. I admit these examples are getting ridiculous. The Beatles zeitgeist was 55 years ago.Why didn't some Hollywood studio release a film of a Super Bowl game the same weekend as "Taylor Swift -- The Eras Tour" and see which one filled more theater seats?
There's no way to judge "Who is more popular". The Beatles and Shakespeare have stood the test of time. Swift will get her chance. Milli Vanilli were popular once and even won a Grammy for whatever that was worth...😑
