The pair have revealed that getting onto the line-up of the Punchestown festival, which takes place from July 9-11, would be their ultimate career dream.
"We would love to do it," Edward told the Herald. "Our fans are all buying tickets for Oxegen because they think we're going to be performing at it this summer. There's all these rumours about it on Facebook and Twitter.
"We would be so much fun. We'd go out into the audience and start mud slides and crowd surfing, it would be so cool. We'd get the strongest people in the audience to help us out and then we'd jump on top of them all."
And they reckon they would prove just as entertaining as artists such as Eminem, Arcade Fire, Jay-Z, Prodigy and Black Eyed Peas.
"Every year at Oxegen, you have all these artists singing their same ballads and songs but it's a festival -- people are meant to go crazy and we would get the whole crowd to go mental," he added.
This week the quiff-haired twins will play Waterford, Killarney and Cork before coming back to the capital city to perform at Vicar Street on April 18.
