Mick Konstantin’s viral sensation ‘There’s Only One Conor McGregor’ has proved to be the unofficial soundtrack of the McGregor vs. Mayweather fight build-up.

The song, which has risen to the summit of the music charts in Ireland, was released little more than a couple of weeks ago and has captured the imagination of everyone from fight fans to Conor McGregor alike.

In fact, to thank Konstantin for his efforts, McGregor has arranged for the 24-year-old school teacher to fly all expenses paid to Las Vegas this weekend to witness the biggest combat sports spectacle in history. To return that favour, the Kildare man has pledged to donate all the proceeds from the release of the song all the way up to fight night to a charity of McGregor’s choice — the Crumlin Children’s Hospital which does so much good work for the community from which McGregor was raised.

TheMacLife.com invited Konstantin to SBG Ireland recently to shoot a performance of his song and you can see his efforts below.

You can purchase a copy of the song (for a fantastic cause) via iTunes.
