Without the plausible threat of action, you will be ignored. Action could be violence (eg: throwing a brick at a cop), or economic (eg: we're all going to stop working for you, we're all going to stop spending money at your business). But there needs to be something.
When it's just "we meet up for an hour on saturday, sing, and go then home," that's just not very effective on its own. You can sing and dance, but there needs to be a backing of "If you don't treat us well, we can hurt you" if you want to be taken seriously.
