Snoop Dogg unleashes the next visual off his current Doggumentary, and this one's a true meeting of legends as the Doggfather teams up with folk icon Willie Nelson for "Superman." It sure is no coincidence that this clip arrives on 4/20. This video features onstage footage, along with the duo goofing off in the studio. The clip's highlight is probably Snoop Dogg's attempt to sing instead of rap. Enjoy!
