Gretchen Wilson, Big & Rich and Cowboy Troy have collaborated on a patriotic single that will be available for free download later this week. "Our America" finds the artists singing and speaking intermingled lines from "The Star Spangled Banner," the Pledge of Allegiance, the Declaration of Independence and Martin Luther King Jr.'s historic "I Have a Dream" speech.

A free download of the song will be available July 1-5 at OurAmerica2005.com, a site sponsored by Chevrolet. The timed-out download can be listened to through the summer and will expire on the U.S. Labor Day holiday (Sept. 5).

The MuzikMafia artists will perform the song July 4 backed by the renowned Boston Pops during the orchestra's nationally broadcast annual "Boston Pops Fireworks Spectacular." The show will air live on CBS at 10 p.m. ET (tape delayed on the West Coast).

The track, which will also be serviced to U.S. radio stations for airplay consideration during the U.S. Independence Day weekend, will be included as a bonus track on the sophomore albums from Wilson and Big & Rich, both of which are due later this year.

As previously reported, Wilson's "All Jacked Up," the follow-up to last year's smash "Here for the Party," is due Sept. 27 via Sony Music Nashville. Big & Rich's as-yet-untitled new album is scheduled for a Nov. 8 release from Warner Bros.

Big & Rich and "hick-hop" country rapper Cowboy Troy are touring together into the fall, playing their own shows, festivals and opening for Brooks & Dunn. Wilson, meanwhile, is also playing festivals in the midst of her summer tour with Kenny Chesney.
