The best thing would be for songwriters (most of whom do not generate income on a collectable level anyway) to waive royalties for live performance altogether. We could then establish a very strong argument for getting the PRS out of smaller venues completely. The cost of collecting royalties for songs, which may only be performed at ten venues a year anyway, far outweighs any advantage, which might accrue to the performers. Better by far to keep gigs open and music live. That would benefit singers, writers and organisers alike.
