Irish fella behind the McGregor song will play a huge gig in Vegas on Friday
Fair play to him...
It's been a busy few weeks for Mick Konstantin. He has risen from relative obscurity to a viral star online in the space of a few short weeks.
It's the story that just keeps on going. First he shared a song he wrote which received almost four million views online in just two weeks.
It caught the ear of McGregor himself who organised for Mick to be flown out to Vegas to attend the fight with a friend.
Numerous appearances on TV and interviews followed on including an appearance on our very own JOE Show and now, possibly his biggest moment yet has arrived.
It's been announced that Mick will perform his very catchy tune about McGregor at Friday's weigh ins for Conor McGregor's fight with Floyd Mayweather.
The UFC shared the news but allowed Mick to reveal the news himself in the early hours of this morning.
The UFC said: "Attention fight fans, Mick Konstantin is going to be at the T-Mobile Arena at 11am before weigh-ins. Be there."
On the off chance that you haven't heard his song yet, you can listen to it in full below, it's well worth a couple of minutes of your time.
