Are these wines beyond their prime?

My hubby knows someone that was given 4 bottles of wine and he needs to know if they are worth keeping. 1) 1977 Kalin Cellars Pinot Noir 2) 1970 Chateau Kirwan Grand Cru Classe Margaux 3) 1973 Pavillac Chateau Clerc Milon Philippe De Rothschild Red Bordeux & 4) 1967 Beaujulais Region of Bolly(sp) Red Beaujulais. Thank you in advance for any help.
