"They lived through this incredibly intense period, where they’re under all this scrutiny, all this pressure. The logistics are wild and, in some instances, a little threatening to their health and well-being. Out of necessity, they’re inventing the stadium concert tour. It was because the police kept saying, 'If you play a place that holds 8,000 people, it means we’re going to have 38,000 people outside. You’ve got to play in bigger places.' So they sort of invented the arena tour before technology could support it, really."
Said the movie director Ron Howard, who has a new documentary, "8 Days a Week," about The Beatles in their years of touring and performing live.
It was 50 years ago Monday that The Beatles played their last live concert — last official concert — a mere 30 minutes, crammed with 11 songs and constant fan screaming. It was in San Francisco, in Candlestick Park. The last song was a cover song, Little Richard’s “Long Tall Sally.”
They did play an additional concert, on a rooftop in 1969, as seen in the movie "Let It Be," which isn't available on DVD, not officially.
