Fans were delighted by the collaboration, with many taking to Twitter to praise the musicians:
Their Britpop rivalry was legendary, but Noel Gallagher and Damon Albarn have put their musical differences aside to perform together in aid of a cancer charity.
The Oasis and Blur singers strummed their guitars alongside each other on stage at London's Royal Albert Hall as part of the Teenage Cancer Trust series of concerts, curated by Gallagher.
They were joined last night by Blur guitarist Graham Coxon for a rendition of the band's 1999 hit song Tender, with Paul Weller adding to the star-studded line-up by playing the drums.
English National Opera are due to reveal their latest project aimed at inspiring the next generation of opera-lovers later.
They have recruited ex-Blur frontman Damon Albarn to try to appeal to a younger audience.
Blur's lead singer Damon Albarn is to release a new solo album in May. It is called 'Dr Dee' and is inspired by the life of John Dee, a mathematician in the time of Elizabeth I. The BBC Philharmonic Orchestra also perform on the album.
