First of all sorry for my bad english, I'm looking for an old animated film wich tells the story of a girl and her differents boyfriends during the 60´ and 70´, I can remember that one of them went to the vietnam war and when he returns he will take drugs or whatever... during the whole film u can listen famous songs from the 60 and 70 maybe 80 too... the films ends up with the marriage between the girl and the mix of all her boyfriends (the best of each of them)

Sounds kind of like Across the Universe - but its not animated
