The balding, bespectacled nebbish who gained cult status as the oddball Larry "Bud" Melman on David Letterman's late night television shows has died after a long illness. The Brooklyn-born Calvert DeForest, who was 85, died Monday at a hospital on Long Island, the Letterman show announced Wednesday. He made dozens of appearances on Letterman's shows from 1982 through 2002, handling a variety of twisted duties: dueting with Sonny Bono on "I Got You, Babe," doing a Mary Tyler Moore impression during a visit to Minneapolis, handing out hot towels to arrivals at the Port Authority Bus Terminal.
I'm surprised because I remember seeing him as a kid in various TV ads (can't for the life of me remember which). And then much later on when I started watching Letterman around 1995 I was amazed to see him still alive.
