You may have heard that one track, ‘Happy’, the Despicable-y popular Pharrell chorus (not song) on the radio nearly non-stop for the last few months. Longtime music goof “Weird Al” Yankovic has erupted with a star-studded cast to cover ‘Happy’ in his own special way: ‘Tacky’. Watch the video, clap along. Yankovic’s 14th (what!) album drops tomorrow, titled Mandatory Fun.
