Irish singers Glenn Murphy and Ronan Scolard, whose Adele mash-up saw them join the star on stage during her second of two sold-out Dublin concerts, recalled the "amazing" experience on The Ellen DeGeneres Show and performed their viral medley for her audience.

It was revealed earlier this week that the duo would be flying out to Los Angeles to appear on the hit talk show with Murphy taking to Facebook to say: “After what can only be described as a complete whirlwind, Ronan and I are about to board a flight to LAX to appear on The Ellen DeGeneres Show later this week.”

Scolard also posted about their latest adventure, saying he and Murphy were "absolutely buzzing" as they board their flight to LA for the high-profile gig. 

Speaking with Ellen, the pair revealed that many of their friends had speculated about their chances of being called on stage when they were invited to the show by the Hello hitmaker. They never expected it to actually happen, however, with Scolard saying they were "just excited to be there."

Talking about the moment they were called on stage Murphy said, "We both were like 'What!?' and the next thing we knew we were running down these stairs, like five flights of stairs, I have never cursed as much in my entire life. Ronan was so cool and I was like 'Oh my God, oh my God, oh my God."

"I was trying to be calm for the both of us, being like 'right, there's no time for nerves here'. But then, prior to that we had seen the likes of Bono, The Edge, Colin Farrell, Hozier, sitting in the rows just literally in front of us, and that started to sink in and I was like 'oh no, there's a need to be nervous here, this is scary'," Scolard added.

Before performing their medley, Ellen presented the lads with special tricolour underpants with "Ellen loves Ireland" printed on the back.
