That story is true, but MArtin’s wife loved to throw parties, Dean would come for about an hour then go to bed to play golf. He called the police several times on his wife’s parties just to get them to break up and people to go home so he could sleep.
Also it was a rarity for Sinatra to ever be at Martin’s house, he was basically a recluse and never cared for anyone to come over, especially Sinatra.
I watched an episode of Match Game (from the 1970s) recently and someone mentioned Martin’s drinking was for show (exaggerated). I forget which celeb said it.
