Broadway's recent revival of Frank Wildhorn and Leslie Bricusse's Jekyll and Hyde, starring Constantine Maroulis and Deborah Cox, closed too soon. But perhaps they would have run a little longer if they'd included a Liza cameo. In this clip, Ms. Minnelli gives a soaring performance of one of the show's most touching tunes. It's the kind of mesmerizing video that sucks you in and won't let go.

Also worth noting — especially if you find yourself getting sucked into the YouTube vortex that is Liza Minnelli videos: Somehow her hairstyle is always perfect for the decade, without actually changing at all.
