Indie-pop duo Tegan and Sara have opened up about recording a song for the brand new film, 'The Lego Movie', and explained they were surprised to get the call about working on the track called 'Everything Is Awesome'. 

Speaking to Rolling Stone magazine about being asked to contribute a song to the project, the stars admitted that when the gave the team their finished demo they didn't think it would be selected for the film: "I thought we did a terrible job. I think it was in a different key. Then we stepped it down because I was just shrieking. Mark, the technician, was like, "It sounds like you're screaming," I said, "I am!""

"[Laughs] We were like, "There's no way we'll get it." So we were really thrilled to hear our version got in the credits. And I love the Lonely Island, so I was pretty excited that they picked us because they were like, "Oh, we're throwing it out to a bunch of different people." It was, like, big rappers, and I'm like, "There's no way."

"The only vocal suggestion that they made was that we should sing it with as much excitement and jubilation as possible. Even though the movie ends in sort of a strange way, the lyrics are very, "Even though things are going badly, I'm still excited, I'm still happy," and I kind of love that."
