Music Sam Smith Covers Whitney Houston’s “How Will I Know” by Emily Exton 6/20/2014 Embedded from www.youtube.com. </noscript> </div> Passionate Grey’s Anatomy fans will recognize Sam Smith’s take on “How Will I Know” as an episode-ender from this past season, and now they can revel in telling their friends they heard it first. The full version of our You Oughta Know artist’s cover hit the internet today, and it’s the perfect way to end your summer Friday (as long as you’re cool with shedding tears in public). It’s also doubly satisfying: we get to wrap ourselves in the warmth emanating from Sam’s vocals and the 22-year-old lad gets to pay tribute to one of his idols. As if personal shout-outs from Eric Stonestreet weren’t enough. Everything’s coming up Smith these days! [Photo Credit: Jen Marigliano/VH1] Emily Exton
