I don't know, Steve. I reckon that line was intended to show just how stifling the young woman's life was with her infantilising parents. As are 'How could she treat us so thoughtlessly? How could she do this to me?' The point of the song seems to me to be that the woman is now a grown adult and has needs her clingy, suffocating parents won't or can't accept.

Interesting, meself, about the Montreal connection. London was just beginning to be trendy (Carnaby Street and all that) and I was bemused when my accent (quite Cockney then!) threw people into raptures in Canada. I was staying with my aunt in London Ontario after the Expo trip, and people kept coming up to me in the street asking me to 'Say something!'
