Haggard released the duet album "Pancho & Lefty" with Willie Nelson in 1983, with the title track becoming an enormous hit for the duo. In 1987, a second, less successful LP, "Seashores of Old Mexico", was also released, and the pair worked together again with Ray Price in 2007, releasing the album "Last of the Breed". In 2015, they released their sixth and final duet album, "Django and Jimmie". The album's lead single, "It's All Going to Pot", was a subtle reference to smoking marijuana, and the music video for the song showed Haggard and Nelson smoking joints while singing in a recording studio.
