The Oasis reunion could come earlier than expected. The Britpop-era band ended a 15-year hiatus last week by announcing a tour of the British Isles next summer, with 17 gigs selling out on Saturday following a scramble for tickets by Oasis fans. Liam is slated to perform some hits at Wembley Stadium in London on Sept. 21 ahead of the world heavyweight title fight between Anthony Joshua and Daniel Dubois, when more than 90,000 spectators are set to attend.
