McDonald's isn't necessarily known for its super emotional commercials, but their most recent one will definitely get you reaching for the Kleenex. It's a compilation of the various signs displayed at McDonald's franchises around the country. From "Boston Strong" to "A Little Lovin Can Change a Lot," the signs range from powerful and sweet, to funny and personal. There's a song playing in the background, that's super poppy and fun with inspirational lyrics. It's sung by a few different voices, kind of like a choir. So, what's the song?

The song is a cover of 'Carry On' by the band fun. fun are an American indie pop band based in New York City. Founding member Nate Ruess first saw success with his band the Format, before they eventually called it quits in 2008. He later joined forces with Jack Antonoff -- who is currently dating Lena Dunham -- and Andrew Dost. The band has gone on to achieve huge mainstream success with their songs 'We Are Young,' 'Carry On' and 'Some Nights.'
