Imelda May says she had to brush up on Amhrán na bhFiann after getting a last minute call up for Conor McGregor's historic boxing bout. 

May was given 24 hours notice to be in Las Vegas to sing the national anthem as the world geared up to watch McGregor take on Floyd Mayweather. 

Newstalk Breakfast's Shane Coleman, Kieran Cuddihy and Ross Lindsay discussed the performance this morning. 

The only positive Shane could glean from the performance was that it wasn't Ireland's Call that was belted out.
