"just enriching the megastars as we cynically assume."

Err, it's a pro-rata system, so I don't think this really applies (although I know folkies love to believe it)!

I've done very nicely out of my modest scribblings. I'd have hit the buffers years earlier if it wasn't for PRS. I think I get a fair cut for my endeavours. The megastars are performing to, and recording for, millions, so they get commensurably more. That's fair, I think.

And yes, the GACS scheme applies to arrangers as much as writers. You get 100% for your own performances of your own arrangement (it's split with Anon, who doens't bother to collect his share so you get the lot), just as song and tune writers do.
