Once, long long ago, Oasis’ Noel Gallagher said Blur’s Damon Albarn and Alex James would “catch AIDS and die,” and thus began a decades-long, mostly media-fueled feud between the two bands. This weekend, though, hell froze over and Gallagher and Albarn appeared on stage together—playing one of Albarn’s songs, no less. The duo, along with Paul Weller and Albarn’s bandmate Graham Coxon, played Blur’s “Tender” at a benefit concert for the Teenage Cancer Trust, because apparently kids with cancer don’t really care if a couple of adults have been assholes—or arseholes, in Gallagher-speak—to each other.
