David Letterman:”A Life On Television” Airs Tonight On Channel 5! [VIDEO]

Get a sneak peek of tonight's salute to one of television's greatest.

At 9:30 tonight CBS will air a 90 minute special looking back at the long and brilliant career of David Letterman, as he gets ready to ride off into the sunset on May 20th.

Ray Romano is the host and the show will feature the part that I am most excited to see, old clips from the NBC days when Dave was at the very top of his game.

So kick back tonight, turn on Channel 5 and relive old clips of Bill Murray, Stupid Pet Tricks, Dave's return from quintuple bypass surgery and more.

Get a preview of what promises to be an awesome trip down memory lane.
