Not just the Fish Cheer*: I've just in the last couple of weeks heard Country Joe's Fixin' to Die Rag, including a new extra verse to update it. Sadly I don't do shorthand, or I'd reproduce it here.

The old folkies remember. Don't pass on the torch: pass on the flame.

* Personally I prefer the augmented version, as perpetrated at Woodstock. Much more apt.
