Or, search our Digital Tradition Folk Song Database (upper right corner of this page) for @camp, or @kids, and you'll find a wealth of songs.
Click here for a previous thread called "Songs for Scouts."
Now, if you want to get obnoxious or maybe a bit raunchy, try the "Naughty Kids" threads here and here. Oh, and click here for the "Prairie Home Companion Camp Songbook."
Hope that helps.

Say, I'm trying to find a copy of the Oak Publications 100-something plus five camp songs book - anybody wanna sell one?
