You know, the guys who play the trombones and the drums and such while the crowd cheers. Are these people employees of the team? Sub-contracted professional musicians? Fans who auditioned (and if so, do they get paid)?
Also, do the crowd chants erupt organically, or is there a conductor (so to speak) initiating them?
If you’re not an MLS fan but a European (or elsewhere) fan, please feel free to explain your league’s procedures.
Thanks!
