After performing their postponed concert in Cincinnati at midday, The Beatles flew 341 miles to St Louis, Missouri, where they performed one show at 8.30pm.
The concert took place at the Busch Stadium, and was seen by 23,000 people. The support acts were The Remains, Bobby Hebb, The Cyrkle and The Ronettes.
The show took place in heavy rain, with a makeshift shelter over the stage to protect the musicians, although water still dripped onto the amplifiers. It was this incident which finally convinced Paul McCartney that The Beatles should cease touring.

They sang, danced and got soaking wet while their four idols, Lennon, George Harrison, Paul McCartney and Ringo Starr, performed for 30 minutes under a plastic canopy.
Some fans, including 85 who won flights from Denver in a radio contest, had come a long way for the show. Tickets were pricey, ranging from $4.50 to $5.50.
After the show, about 50 young fans scrambled to touch the Beatles, who departed in two police cars.
A 17-year-old girl from Creve Coeur managed to hug Starr for a moment. Afterward she kept shouting, "I held him, I held him."
