Mike Viola teamed up with John Oliver and Will Ferrell on a new song for Last Week Tonight, the late-night talk show hosted by John Oliver.
Being a longtime fan of Viola, Oliver called on him to write a parody of Lee Greenwood's "God Bless the U.S.A." Viola's version aired this past Sunday with a performance by Ferrell.
