The gig at the Olympia is tonight, with heaps of Irish stars taking to the stage to play Aslan tunes. Horslips, Shane McGowan, Paul Brady, Ryan Sheridan and U2 are all set to put in an appearance. Tickets have been sold out for weeks, but the show is being streamed live to over 100 bars and cinemas across the world including South Africa, Dubai, Australia, America and Canada.
Christy Dignam himself is vowing to perform even though is courageously battling cancer and proceeds from this concert will help pay his medical bills.
All the stars involved will be singing a classic Aslan track.
U2 will perform "This Is" live from their studio in New York which will be beamed to the concert at the Olympia and streamed across the world.
And Aslan's Billy McGuinness said the band are delighted that their old rivals have signed up to support Christy.
He said: “It's amazing – I would never have believed U2 would do something like this and we are delighted and thrilled.
“I want to thank Bono, The Edge, Adam and Larry personally as it is really nice that they are taking time out from recording their own album to help Christy.
“It has blown us all away.”
