Oasis and Blur have a storied history of name-calling and fallouts throughout the 1990s, a rivalry which peaked via a chart battle when the former's single "Roll With It" came out on the same day as the latter's "Country House" – dubbed the 1995 ‘Battle of Britpop'. The Albarn-led group eventually nabbed the No. 1 spot on the U.K. Singles Chart.

The long-anticipated Oasis reunion tour is finally underway, with the famed brothers taking to Cardiff's Principality Stadium last Friday, July 4. But fans are being warned about doing one thing after seeing their idols during the tour - as it could cost them hundreds.
