David Letterman's tribute to Robin Williams - a keeper

David Letterman and Robin Williams go way back, as fans of both know so well, and it was with genuine anticipation that I awaited Dave's tribute (the show was dark last night). He did not disappoint: It was warm and genuine and interesting and foremost brought to mind something that a few obits overlooked last week: Some of Williams' classic work was right here at “Late Show,” and at “Late Night” and “Tonight” as well. Dave didn't tear up — he's not a teary guy — but watching this you certainly knew that a major loss, indeed tragedy, just took place in his life too. A wonderful tribute, well worth watching.(If you are coming to this post via Newsday.com/tvzone, click on the headline to see the clip.)
