ok - Neil Young and Robert Duvall
Neil Young appeared on Late Show with David Letterman (1 episode, 2006)
I believe Robert Duvall appeared on the same show with Neil Young and David Letterman (1 episode, 2006)
I checked the imdb and it shows both Neil and Robert on the first show of 2006
Next -
Raquel Welch and Tommy Lee Jones
