My mate's band did a rocked-up 3 guitar cover of Eleanor Rigby at their christmas gig
Everybody kept requesting it at subsequent gigs but they only played it a couple more times as they hadn't asked permission or anything and I think they were bricking it a bit about getting reported.

I shouldn't think they would have anything to worry about.

I might be letting myself in for a proper kicking here
but wasn't Eleanor Rigby by the Beatles? Were Macca and Ringo really likely to give a shit?

No, nor were they losing any money or having their copyright infringed.
The PRS will see them alright anyway.
