In 1989, artists from Pink Floyd, Queen, Rush, Deep Purple, Black Sabbath, Yes, Iron Maiden, Free and others joined forces to raise funds for people affected by the Armenian earthquake. Kerrang called it "the greatest array of hard rock talent every assembled".
Organised by Jon Dee, the remake featured David Gilmour, Brian May, Tony Iommi, Ritchie Blackmore, Alex Lifeson and Chris Squire on guitars. On vocals it had Ian Gillan, Bruce Dickinson, Paul Rogers and Bryan Adams. Keith Emerson and Geoff Downes played the keyboards and Roger Taylor played the drums.
The song was released worldwide - it successfully raised funds to rebuild a children's music school in Gyumri in the Armenian earthquake zone. Today the new school teaches music to 220 children a year!
