Guest - I think the line should be "If you want to have a good time jine the cavalry" (Which is from "Jine the Cavalry")

It goes on with lines like "if you want to chase the devil, if you want to have fun,if you want to smell hell, jine the cavalry!"

I don't have the whole song in front of me or I'd print it here.
Of course that could be an anti-war version you have ?!?
