We'd been waiting for this one to come along. Seattle's dj100proof comes through with the inevitable mash-up of Pharrell's massive hit "Happy" — which has gotten a lot of love from Cameroonian and Cotonou video remakes —  with Fela Kuti's "Colonial Mentality" from 1977's Opposite People/Sorrow Tears and Blood. As dj100proof writes on his website, "I thought the shuffle tempo, driving bass lines and horns of Fela Kuti could provide a nice backdrop, so I chopped up his classic." Download his blend of Fela Kuti and Pharrell in "Happy Mentality" below.
