The musical version of Little Shop of Horrors debuted off-off Broadway in 1982 and starred Lee Wilkof as Seymour and Ellen Greene as Audrey. The following year, the two of them and other cast members taped this spot for the annual Jerry Lewis Telethon for MDA. The video is wonderful for many reasons, starting with the fact that it captures part of their great performances. It was also done at the Ed Sullivan Theater, later the home of David Letterman's show and now Stephen Colbert's. And it's also kinda nice to see that a sadistic man-eating plant, determined to devour every man, woman and child on Earth cares enough to raise funds to fight Muscular Dystrophy…
