It's complicated, but to try and give you an idea:
On Wednesdays, everyone tries to practise their own parts of all the different songs, and there's little talk. Tickets are mostly state funded, so are only £45, and the band call themselves The Iannis Xenakis Music Ensemble that night.
Thursdays, the atmosphere gets to be a little more relaxed. People to some degree know their parts, and we now try to play together. Tickets are largely beer revenue, cigarettes revenue and silly French hats revenue funded, and are £30. This night, we call ourselves The Jazz Messin' Jars.
Fridays, we normally play well enough together, kinda, and sell £5 tickets at our local Duck&Dog as Ducks and Covers.
Saturdays, everything should normally be perfect, and we set up for the possible slight finishing touches long before the happy couple arrive, and we will that night perform for a fixed £800 as Groomed and Bridled.
That's £100 a piece! Brill!
