Walkout Music

Will McGregor stick to his usual Sinead O’Connor “Foggy Dew”/Notorious B.I.G “Hypnotize” mix, or will he innovate? Friyie’s “Money Team” is the obvious choose for Mayweather. Money Team is also the name of his brand and a name he will definitely want to promote.

Attire

Will Floyd try and mess with Conor’s head and wear Irish colors to the fight? (As revealed on Showtime’s All Access, Mayweather has a custom made tri-color mouthguard in his collection!) With the eyes of the world on him, McGregor, who is a fashionista, may try and use the opportunity to maximize his commercial potential.

Anthem

While there was initially some talk that Bono would sing Amhrán na bhFiann at tonight’s fight, the U2 frontman was double booked. It has since been revealed that Irish singer and songwriter Imelda May will sing the Irish national anthem at the T-Mobile Arena. Pop star Demi Lovato is confirmed to perform the Star-Spangled Banner.

Stare Down

It will be interesting to see what happens during the face-off in the center of the ring tonight. Conor McGregor was an incessant screaming machine at last night’s weigh-in. Will he pull an all-business poker face before the first bell?

The odds are stacked against the Irish man, but his self-belief knows no bounds. Will it be McGregor or Mayweather to throw the first punch? Mayweather has decades of defensive skill on his side, but McGregor has a left hand that has been defined as a game changer. Can Conor land the big shot, or will Floyd toy with him like a novice?

Can Conor McGregor do it? Who knows? All we know, is that tonight, the eyes of the sporting world will be fixed on an Irish man taking on a monumental challenge.
