I've been in a number of bands, generally totally democratic apart from those containing school teachers. (oh dear, but it's true)

Last night someone said to us "Who's the leader?" and we all said "No-one".
We all get on really well with very few tensions of any kind, and have done for many years, whereas bands with "it's MY band" leaders seem to fragment more easily.

Does a democratic band have more chance of lasting longer?
