If you haven’t come across Kildare native Mick Konstantin, then you must be living under a rock.
After his song that he wrote and recorded, ‘There’s Only One Conor McGregor’, went viral, and soared to the number one spot in the charts, Konstantin has been on radio and TV stations galore.
Watch the announcement here:
When McGregor got a hold of the song, he decided to ship Konstantin over the Vegas for his fight against Mayweather tomorrow, August 26.
All proceeds made from the hit are going to Our Lady’s Children Hospital in Dublin.
The Celbridge man will perform to a packed crowd in the T-Mobile Arena in Las Vegas at the weigh-in, 7pm Irish time tonight (August 25).
