Were they selling Merch at the gig? Nice earner for a lot of bands
other costs:
Agent will take his/her fee
If band has a manager they’ll take a cut too of course
Roadies wages
Travel from uk
Etc etc
I always wonder how it works. 500 capacity , 66 euro per head. That's 33k in ticket sales. How much goes to the band - surely 25 to 30k in this instance and the venue makes a couple of thousand plus alcohol and drink sales. The promoter would look after hotels etc for the band and crew ?
