Olly Murs was starstruck by some of the other acts on the Band Aid 30 single.

The 'Troublemaker' hitmaker admits it was a surreal experience to be in a studio with the likes of U2's Bono and Coldplay's Chris Martin while recording an updated version of 'Do They Know It's Christmas Time?' at the weekend but quickly got over his nerves and set about the task at hand.

Asked if he couldn't help but be amazed by his fellow singers, he said: ''I think that was what it was like for the first half an hour.

''And then you need to get to the job. And the job we had was to sing, and sell this song.

''So yeah, first, initially, it was like, 'Wow, I'm in a room with Bono and Chris Martin from Coldplay,' but in the end you get over that and, you're like, 'It's time to get focused and get this song out there and do a good job on that.' And that was the aim.''

Olly had an ''amazing'' experience recording the track - which will raise money for the Ebola crisis in West Africa - with the likes of Ed Sheeran, One Direction, Ellie Goulding and Paloma Faith and is honoured to be a part of history.

He told Billboard magazine: ''You know what, it was great to come together with loads of other English acts and artists. It was amazing. We really had a good time doing it. The video, everything: It's incredible.

''Just to be featured on the song is great. I'm just really, really pleased. It was a really special moment for me and my family. I just really hope people around the world get behind the song.''

And the 30-year-old star confirmed no one knew which line they had been given on the song until they saw the completed video.

He said: ''No one knew. Even when they left [the studio]. We all just sung the song once or twice around. We just waited to see the video and saw our parts then.''
