> Both songs are about going to "The Bay".
But in the English song, "the Bay" is an actual place in which the singer and a particular addressee have vacationed in the past, and in the French song, "the Bay" is an imaginary place which the singer invites a generic audience to indulge in.
Speaking of which, the English song is notionally sung to someone known to the singer, and the audience is conceptually overhearing it, while the French song is sung to the audience.
The two songs don't have anything in common. They both compare their bay to Berlin, London, and Paris, in the sense of saying that the Bay is not any of those places. Mount St. Helens is also not Berlin, London, or Paris. Have I just made a second translation of The Bay into English? Does it make any difference that Mount St. Helens is a volcano?
