(fortunately, "The Orchestra Song" was the subject of another thread, so I don't have to ask the dumb question after all...)
I always thought that the best thing about camp was singing songs that made harmony. Like "Swing Low Sweet Chariot". It just never sounded the same with only four of us to sing it. And we could only do four parts instead of eight for "Warsaw the Forty Second". But I still remember all those car trips with great fondness. Better than my sisters do, I think!
