Maurice Hyde / themaninthejar — The Clash Ticket May 27th 1977 Chelmsford Chancellor Hall
Three separate recollections preserve what attendees remember about the night: Ash, Duncan Egleton and Maurice Hyde.
The surviving Chancellor Hall source PDF contains a Tony Rupp promotional advert printed for Sunday May 29th. This is an advert, not the surviving Clash ticket. It helps explain why 29 May appears in older archive material, but it does not override the ticket evidence for 27 May 1977.
The archive therefore preserves both pieces of evidence and distinguishes their roles: the ticket dates the event record; the May 29 advert remains a separate promotional artefact requiring its own interpretation.
The recovered Where & When source index contains a legacy Clash entry recorded as 29.05.77. That source wording is retained exactly as an archival clue. Because the surviving ticket is direct evidence for the event date, the selected Chelmsford Rocks event record now uses 27 May 1977.
This is an example of the archive's evidence rule: stronger primary evidence can determine the working event record without pretending that an older source never said something different.

The recollections contain humour, strong opinions, uncertainty about set lists and different memories of the support bands. They are not merged into a single authoritative story. Where a memory says “I remember”, “I think” or “must have”, the archive keeps that first-person qualification.
This matters because Chelmsford Rocks is not only trying to establish dates. It is also preserving what the people who were there remember about the night.
