UNDATED (AP) – The hip-hop snippet of Chicago’s song “25 or 6 to 4” that was used in a U.S. Army ad is now a full-length song.

Chicago and rapper realnamejames have released a two-and-a-half minute version of the song with new lyrics about finding one’s inner warrior.

The U.S. Army had used an abbreviated version in November for its “What’s Your Warrior?” marketing campaign.

Chicago’s Robert Lamm, who wrote the original song, says it’s exciting to have his song morph into a powerful audio and visual experience.
