The Dubliner, 33, was wrapped in a tricolour and danced with the band, who invited the Dubliner to perform with them at their gigs at the 3 Arena in Dublin in October.

As the crowd began to sing 'Ole, Ole, Ole', singer Brian Warfield said: “What a girl, what a girl.

"You know something, I’m going to invite her to come down to the 3Arena and sing with the Wolfe Tones for the last shows down there in October.”

As well as her boxing prowess, Harrington is becoming known for her passionate singing.

After collecting her second Olympic gold medal at Stade Roland Garros this month, Harrington serenaded the crowd with a rendition of the Irish ballad 'Grace'.

Harrington, 34, announced her intention to retire after this year's Olympics.

"I know now, that's it, done, dusted and what a way to go out," she told Morning Ireland.

"The fact that I know that I am now done, and the fact that I am finishing this way [is great], 'cos a lot of the time people don't know when to finish, and I'm happy that I am making that decision to finish it this way, my way, and go out as a double Olympic champion.

"That's it, that was it, done, dusted, I've nothing more to prove, not even to myself, which is the most important thing."
