WATCH: Mick Konstantin performs 'There's Only One Conor McGregor' as Irish take over Las Vegas
Kildare teacher Mick Konstantin was surrounded by a horde of Irish fans while performing his hit single 'There's Only One Conor McGregor' in Las Vegas.
The 24-year-old was contacted by McGregor's management team after the song was released and told they would like to fly him over for the fight with Floyd Mayweather tomorrow night.
Mick and a friend have headed over with their flights, hotel and tickets all paid for.
And this video of the ukulele player strumming his hit in heart of sin city is sure to get you in the mood for the eagerly anticipated bout.
In an interview last week with MMA Fighting, McGregor said he loved the song and wanted to repay Mick for the effort.
"It was one hell of a song. It's a very catchy song. We actually reached out to the guy," McGregor said.
"I had my people reach out to him and we're booking him a flight, him plus one.
"We're going to bring him over to the fight and get him tickets and put him up in a hotel and I'm going to meet him maybe after the fight.
"I'm going to bring him in as a thank-you for the support.
"What a song - it's the journey in music form.
"Myself and my team, we enjoyed it very much, so we're going to fly him out. Him and a friend."
