Pharrell Williams's track Happy is the gift that keeps on giving.
Just a few weeks ago Pharrell had actresses Meryl Streep, Amy Adams and Lupita Nyong'o up dancing to the catchy track at the Oscars.
And now, thanks to the wonders of YouTube, the song has had a Star Wars re-vamp.
Yep, that's Darth Vader, C-3PO and more favourites from a galaxy far far away totally getting their groove on. Because, who doesn't feel like a room without a roof...
