Pourquoi pas!

Will it be able, to see this film again. Does anybody know, where there might be a copy or a digital release or something? I remember, the Film impressed me very much, when i saw it in the late seventy's, it even gave a new direction to my ethics, if i can say so with my medium bad English and i would very much like to see it again for i.e. just control, if i was correctly impressed that time. It seemed like a revolution, the promise of the possibility of love to more than one with the solution for so many not loved people, that are not loved because love is so restricted. Also maybe the way out of the 68 free love dilemma, cause this way love stays still romantic.
