Well..... I did a year of French in 1955 and I can remember about twenty words of it. I can go into a French cafe and order a black coffee, if that's any help. I spent a few days in Paris in 1989 and I got on moderately well.
In that case, you should be fine.
I once worked with a bloke (1966/70)who smoked Gauloise or Gitane cigarettes. He coudn't speak a word of French beyond "oui" and "non" but when he took out his fags and explained that he was an Aussie, everyone spoke English to him....even those who couldn't speak it!!
