The late-late night Johnny Carson, Tom Snyder died Sunday of leukemia at the age of 71. From 1973 to '81, the ciggie-puffing funnyman hosted The Tomorrow Show, which, natch, used to follow The Tonight Show. In '95 he staged a witching-hour comeback, emceeing The Late Late Show with Tom Snyder after David Letterman's Late Show broadcasts. In '98, he was replaced by Craig Kilborn, but to many, he remains irreplaceable.
