Those who’ve read my earlier post about Sinatra and John Denver know that I believe this might have been one of the most unlikely pairings in showbiz history. And I’m not apt to change my mind on this point at any time in the near future. Nevertheless, video from this period comes in the form of this clip from Sinatra and Friends, a 1978 television special formerly available on DVD that has gone out of print. Sinatra and Denver pair up on September Song.
