I sang this song too, in my performing choir in Melbourned Australia about 15 years ago.

I too didnt know it was from Sweet Charity until today and I like the choir version better than the original too.

We had a more complex version of this again. It had more parts repeated and was quite long. It also had 5 different groups singing at once. I can't believe that after being so heavily involved in the choir for 3-4 years, performing overseas, training to almost military regimes during 'camps' which were really 14 hours per day of training (which I dreaded) I have forgotten so much!!!. I can't even remember what the 'parts' are called when you talk about each 'group' singing a different line from the sheet music and also what these 'groups' are called. I know I was one of the 2 soprano groups. I read the second top line of music which was equally as high pitched as the other soprano group. There was another line for the some pitch I can't remember and one line for altos. Being 5 lines all up. I also can't remember if alto is the lowest pitch for young girls and whether the other 'group' which I can't remember the name of is higher or lower than altos. How sad am I LOL
