Now here's something we couldn't have imagined back in the days of the Blur v Oasis Britpop rivalry. Noel Gallagher and Damon Albarn have proved the old adage that time heals all wounds, as they performed on stage together for the first time last Saturday night at London's Royal Albert Hall for the Teenage Cancer Trust. Check out the video below.

Gallagher and Albarn performed a vocal duet of Blur's 'Tender', aided by Blur guitarist Graham Coxon and - oddly - Paul Weller on drums.

The two legendary music figures were embroiled in a bitter feud in the mid 90's, as tabloids fuelled what was a legitimate animosity between Blur and Oasis. Their relationship cooled in recent years though, and the pair have been spotted together in public on several occasions and have gone on record about their newfound friendship.

It's clearly a long time since Gallagher was quoted as saying he wished Albarn would "get AIDS and die", while Albarn also maintained in the past that they were unlikely to ever become friends.

"I can't make up with Noel", Albarn said years ago. "Britpop would be over and heaven forbid that we'd ever admit we'd all grown up!"

Liam Gallagher, sort of like the Japanese solider hiding in the Philippines for 29 years after the end of World War II who thought the war was still going on, is seemingly none-too-impressed with this news and took to Twitter this morning to voice his disapproval. The 'War Criminal' Liam is referring to was likely Tony Blair, while he couldn't help but issue another dig towards Albarn by calling his band 'Blue'.
