The music video is from 1987, and was made in support of an album that Michael Crawford had just released, performing the songs of Lloyd Webber. Crawford had starred in Phantom of the Opera three years earlier. Joining him here is Frances Ruffelle, who I posted a song from a couple days ago in her supporting role from Starlight Express (though this wasn't one of her own numbers). By the time of this video, she'd since left the show and had created the role of Eponine in Les Miserables.
But here they are together, joined by "Only You" and their connection to Andrew Lloyd Webber.
