Bono famously clasped hands with leaders on either side of Northern Ireland's sectarian divide, Bob Geldof shone a light on Third World poverty and Spice Girl Geri Halliwell ditched her Union Jack mini dress to become an unlikely ambassador for Unicef.
Now Cumbernauld's newest rock band has its very own humanitarian crusade.
The School of Rock, based at Whitelees Primary, sees pupils taught to play standards by The Beatles, The Monkees, The Proclaimers and Lynyrd Skynrd.
They have produced Fair Trade is the Answer, a CD and DVD that supports the work of the Scottish Catholic International Aid Fund and the Fairtrade Foundation. The CD was recorded at Cumbernauld College and ties in with the school's enterprise project on fair trade.
Its lyrics ask: "What's it like to grow food yet starve?" and make a plea to "pay the price that's fair and so lend a hand".
The pupils have written to supermarkets which donated Fairtrade products to the school to ask them to play the CD during the on-going Fairtrade fortnight. They also hope to get some radio airplay.
Singer and guitarist Scott Parker, 11, said: "It's about doing something to help Fairtrade and other people, rather than just talking about it. We're actually doing something that will help and make a difference."
Fair Trade is the Answer is available from Whitelees Primary at pound;3, or two for pound;5.
