On the Road Again Tour
The On The Road Again Tour was the fourth headlining concert tour, and second all-stadium tour, by English-Irish boy band One Direction, in support of their fourth studio album, Four.[3][4] The tour began on 7 February 2015 in Sydney, Australia and ended on 31 October 2015 in Sheffield, England.[5] The tour grossed $208 million from 77 shows, selling over 2.3 million tickets. It became the second highest-grossing concert tour of 2015, only behind Taylor Swift's The 1989 World Tour.
Less than two months into the tour, Zayn Malik left the band. His last performance with the group was in Hong Kong, on 18 March, while he gave his departure announcement publicly during the band's show in Indonesia on 25 March. The group then continued touring as a foursome, and began recording new material that was released in the latter half of that year. This was also One Direction's last tour before a hiatus began in 2016.
