Open-licence assets

Permitted web display is conditional on retaining the stated attribution and licence terms.

Twenty-one location photographs, twelve performer portraits and one performer group photograph have individual records below. The production atlas reuses the documented Silver Street Bridge and North Mymms Park venue photographs, so every location photograph displayed there has an individual record below. This reconciliation checked the recorded images, local credits and linked source records on 20 September 2026. Dorothy Atkinson’s earlier YouTube-frame portrait has been removed from the public site because the original Commons file is still marked for licence review; the source video’s reuse terms need independent verification. The wider artwork audit remains open.
