Snoop Dogg can now include Stevie Wonder on his musical-legend collaboration checklist. His new song, “California Roll,” dropped on Tuesday and features the Motown legend on vocals, keyboard and harmonica.

Produced by Pharrell, the song is a chilled-out ovation to the Los Angeles medical-marijuana program.

In an interview with Yahoo Music, Snoop explained that getting Wonder on board was a bit of a coup and Pharrell was skeptical the 64-year-old would be interested. Snoop tells an outrageous behind-the-scenes story of the process and suggests he may have been the one who actually produced the song.

Snoop Dogg and Pharrell have collaborated on numerous occasions, including the commercial hit “Drop It Like It’s Hot.”

Snoop’s new album, Bush, is set for release on May 12.
