The a cappella guys from Home Free perform a patriotic performance of ‘God Bless the USA’ with Lee Greenwood and the United States Air Force Band.

Lee Greenwood initially published ‘God Bless the USA’ in 1984. After the shooting down of Korean Air Lines Flight 007, Lee, who had always wanted to create a patriotic song, realized it was time to unify the country.

It climbed to the top of the country charts, but it was during the 9/11 attacks that the song became a national sensation.

‘And I’m pleased to be an American, because at least I know I’m free, and I’ll never forget the soldiers who died to give me that freedom.’

Home Free is an American a cappella group that participated in The Sing-Off’s fourth season, winning it. Home Free has been spreading its distinctive sound for years, with members Austin Brown, Rob Lundquist, Adam Rupp, Tim Foust, and Adam Chance.

Today, they will sing ‘God Bless the USA’ alongside famous vocalist Lee Greenwood and the United States Air Force Band.
