So having not answered the question it's neither

It just needs to someone to manage the thing (not 'A MANAGER') otherwise it usually goes wrong

Excited on my new venture though. As an older person it's nice to get together with 20 and 30 year olds and work out a set list and look forward to playing.

I find age is a barrier to joining bands. I still like to rock a bit and I don't necessarily want to play with 50-70 year olds
