The Irish fans are in emphatic voice in Las Vegas.
Ahead of Conor McGregor's fight with Chad Mendes at the MGM Grand, Irish fans broke out into song with this stirring rendition of our national anthem at the Las Vegas venue.
If this doesn't get the blood flowing ahead of tomorrow morning's clash, nothing will.
What a moment.
