Love it or hate it, musical theatre is big business and thousands flock to London's West End and NYC's Broadway (and other venues across the globe) to spend a few hours getting lost in a world of song and dance. One of the biggest, and most recognizable names to come out of that scene is British composer Andrew Lloyd Webber who, famed for smash hits such as Jesus Christ Superstar, Cats and Evita, recently celebrated 40 years in the game. To honor his contributions, ITV put on a TV special celebrating the music featured in his productions and current star of the West End's The Bodyguard, Heather Headley, was tasked with performing one of his biggest hits, "Memory." Having already been performed by the likes of Celine Dion and Barbara Streisand, Heather had some big vocals to live up to, but manage it she did, delivering a truly unforgettable performance of the song. Having obviously learned a thing or two from her time on stage, Heather belted out the track with abandon, conveying the song's emotional depths with ease. Watch a video of the performance below and prepare yourselves for a goosebump-inducing moment around the three-minute mark. You have been warned.
