Topical political protest songs,
may only be performed a few times in a short time period.
Or they might become celebrated standard repertoire like this one has..

But it's best to consider this kind of song as a fluid work in progress;
occasionally/frequently needing essential revision,
as time goes by and circumstances change...

If I think back to protest songs our band wrote when we were immature teenagers in the late 1970s,
They'd need to be completely rewritten to be relevant now.

I'd feel a right pillock if they'd become famous records,
and audiences demanded I still sing the exact version they first took to their hearts..

.. just saying...
