meself/SRS - common courtesy - of course, that goes without saying for me. I'm asking about technical copyright/permission.

Richard - so venues need to complete PRS returns every time a performer performs someone else's song/poem? but then how does that work for events like open mics, where a venue can't possibly know who will turn up and what material they'll perform? and I never notice OM hosts noting these retrospectively on the night. Such performers frequently perform other people's material.
