According to setlist.fm, McCartney added the 1963 track "All My Loving" to the set about four songs in, marking the first time he's played the tune on this tour and the first time he's played it in concert since 2019.
Although "All My Loving" wasn't officially released as a single in either the U.S. or the U.K., it got enough radio play to become a hit for The Beatles. It was actually the first song they performed during their debut appearance on The Ed Sullivan Show in February 1964.
McCartney has one more show in Brazil on Saturday in Florianópolis, with upcoming shows in Argentina, Peru, Colombia, Costa Rica and Mexico. A complete list of dates can be found at paulmccartney.com.
