Error. Ringo's tonsils were not removed until I believe December 1964.
12th June 1964, The Beatles arrived in Adelaide, Australia and were greeted by an estimated 250,000 fans, (the biggest welcome the band would ever receive), who lined the ten mile route from the airport to the city centre. Temporary member Jimmy Nicol was standing in for Ringo on drums who was recovering from having his tonsils removed. More here: http://www.thisdayinmusic.com/pages/the_beatles_down_under
