Looking For “Carry On” by .Fun

Hi there! I have been unable to find a choral arrangement of this song. A few years ago it was sung by a children’s choir for a Mcdonald’s commercial during the superbowl. I really would love this for a project we’re doing at my school. Does anyone have any leads? I don’t mind buying them, but I haven’t been able to find it anywhere!!! I’d appreciate any help you could give me.. THANKS!
