Studio 50, New York City, USA
The Beatles traveled to North America for the 3rd time, and their 2nd full concert tour, departing from London Airport with a lusty au revoir from one thousand fans at noon on August 13th, arriving in New York at 2:30 pm local time and setting up residence at the Warwick Hotel on Manhattan until the morning of the 17th.
Their first engagement - after the obligatory press conference, was the taping of an insert for The Ed Sullivan Show. The Beatles didn't perform any TV duties during their August/September 1964 tour and it was now 18 months since those three February 1964 top-rated spots on Sullivan's Sunday night variety series.
During this morning, the Beatles returned to the scene of their triumphant Sullivan debut, CBS-TV's Studio 50, located at Broadway and West 53rd St, rehearsing from 11:00 am to 2:00 pm and then taping from 8:30 pm, also before an audience. They performed six songs live (the same six in same order that they had played on Blackpool Night Out a fortnight previously): "I Feel Fine", "I'm Down", "Act Naturally", "Ticket To Ride", "Yesterday" and "Help!". There was a clear break after "Act Naturally", the Beatles returning for the final three songs and a different stage setting.
