True. As I've said, in some people's mind, the drummer is the drummer, but the bassist, Organist, and keyboardist are "musicians".
If you take away the keyboardist, and still have the Organist, Bassist and Drummer, you can still kill a service.

But take away the drummer?
Or take away a sick drummer and replace him with a novice?
The drums are the only "necessary" instrument. A service wouldn't be the same without us.
