On January 30, 1969, over two years after their final tour ended, the Beatles staged a pop up concert on the rooftop of Apple Corps, the band's multimedia corporation in London. Though a surprise to passers by and humorless neighboring business owners who called the police, the appearance was carefully planned and meticulously documented for the concert film, "Let It Be."

It was chilly that day, and Rolling Stone reports, "Lennon borrowed Yoko Ono’s fur coat... and Ringo Starr also donned his wife Maureen’s red raincoat."

Fans hoped the event was signaled the band's return after years of discord, but before the year was up, the group had disbanded. The rooftop concert was the band's final live performance.

To commemorate the 50th anniversary of the concert, community radio station KOOP has teamed up with the Austin Public Library to present a concert with Austin's favorite simulated Liverpudlians, the Eggmen. The band will recreate the Beatles' set from the Rooftop concert from noon to 1 p.m. on Wednesday, Jan. 30 on the Austin Central Library rooftop garden. The event is free and open to the public and if you can't make it to the library, KOOP will live stream the event on 91.7 FM. More information.
