Last night The Killers took to the RDS, to perform in front of 20,000 excited Irish fans.
During the set, The Killers front man Brandon Flowers, spotted a sign in the front row.
It's now a tradition at The Killers gigs to invites a fan on stage, if they have a sign asking to play an instrument.
Danny, was lucky enough to rock out with the band on stage at the RDS, to their song, 'For Reasons Unknown'.
Check out the full song, featuring Danny.
Lucky man Danny!
