Madame Rosa, indeed.
Reminds me of the old Jackson Browne tune, “Rosey”. After playing it on the radio for a couple of weeks, I was very surprised to learn what it was really about.
I always listened to the melody to do the segues; didn’t pay as much attention to the lyrics.
Common enough. Rockers seem to like leaving their lyrics obscure so that anyone who thinks they've figured them out can feel in the know. And the conclusion is always that it's about sex or drugs.
