Willie Nelson and Merle Haggard's album Django and Jimmie has hit No. 1 on the Billboard Country Albums chart, just days after its June 2 release.

Nelson and Haggard last had a No. 1 album together in January 1983 with the release of Pancho & Lefty. The new album is also at No. 7 on Billboard's 200 Bestselling Albums chart.

"The chart-topping success of Django and Jimmie is another milestone in the remarkable journeys of Willie Nelson and Merle Haggard" Legacy Recordings President Adam Block says. "Their latest achievement is a testimony to the ongoing vitality of their careers, the timeless quality of their music, and, most importantly, the enduring bond of their friendship."

The album, which was produced by Buddy Cannon, features 14 new studio recordings from the country outlaws, including the title track's tribute to jazz guitarist Django Reinhardt and Jimmie Rodgers and "Missing Ol' Johnny Cash," which honors the legacy of the Man in Black.

The duo has released a number of projects together since Pancho & Lefty. In 1987, they put out Seashores of Old Mexico, followed by 2007's Last of the Breed with Ray Price. Haggard also penned "A Horse Called Music" as the lead track on Nelson's 2012 album Heroes.

Django and Jimmie is available for download on iTunes and Amazon.
