Unpossible!
Almost always (can't remember last time I didn't).
And I have very little patience for drummers who poo-poo click tracks. Not coincidentally they're almost always the ones with meter problems.
My experience as well. The better the drummer is at keeping tempo, the more likely the will want a click. The ones that are all over the map swear the don't need one.
This really goes for all musicians though. Any good musician will be able to play to a click effortlessly.....
