there are 300 shows, would likely get blocked by the server or download all of them slowly. Not a huge benefit to doing that.

allSettled would be better too, because if 1 show failed, the whole jig is up

good point on the allSettled - haven't had to use it yet to be honest, so doesn't spring to mind!
