DougR...YES! That is what I just transcribed the song from! I loved the movie so much I went out and bought the cassette the next day!
My daughter almost wore the tape out and I am lucky she left it when she moved out! I have had a less than enthusiastic review from others I've recommended it to, though. I think one has to have an appreciation of "torch" songs, the old time "theatre", as well as really great Irish tenors, along with a quirky sense of humour; the kind that can appreciate the subtleties along with the outright. Some people I know won't watch any movie which has singing in it!
I am sure you didn't "go wrong" anywhere. A few years from now, she'll probably watch it, again, because of some friend's recommendation and call you to say she can't believe she didn't like the first time round!
BTW: Wullie & DougR: if you go here you will find the soundtrack and can even listen to a bit of the title song, instrumental only, if you have realaudio.
