The Muppets are readying for their big comeback with the November 23 release of a brand new feature film, The Muppets. In honor of everyone's favorite puppet crew, Broadway.com is flashing back to a series of our favorite Broadway Muppet Moments, in which stars of the Great White Way sing showtunes and share jokes with Kermit, Miss Piggy, Fozzy, Animal and more. When Liza Minnelli stopped by The Muppet Show in 1979, she found herself in the middle of a "Muppet Murder Mystery." During the thrilling shenanigans, Minnelli opted to use her Oscar and Tony-winning acting chops to help snoop out the culprit by faking her own death. When the guilty party stepped forward, the actress revealed her scheme with a show-stopping rendition of Gypsy's "Everything's Coming Up Roses." This is must-see muppet madness!
