| The Who | 23 Jan 1965 | Corn Exchange | Peter Searles oral history discusses The Who as a support act and the Corn Exchange/top bands of the 1960s. | Useful independent scene corroboration; the oral history does not itself supply the dated event. |
| Jimi Hendrix | 25 Feb 1967 | Corn Exchange | Corn Exchange venue dossier and wider 1960s scene layer. | Dated event remains the principal record; no extra date inferred. |
| Pink Floyd | 23 Sep 1967 | Corn Exchange | Corn Exchange venue dossier and 1960s scene evidence. | Event-level record retained separately from general scene context. |
| The Clash | 29 May 1977 | Chancellor Hall | Paul Cleary and Ian Fortnam oral histories independently describe Chancellor Hall and Chelmsford's punk scene. | Strong venue/scene intersection; oral histories do not replace the dated event record. |
| The Vibrators | 26 Jun 1977 and separate 7 Jul 1977 entry | Chancellor Hall | Chancellor Hall event layer, surviving source/index material, and supplied Pure Mania tour poster listing 26 June. | The poster directly corroborates 26 June day/month: the “26th” is in the June section of the tour. The separate 7 July record remains distinct and is not silently reconciled away. |
| The Damned / 999 | 6 Nov 1977 | Chancellor Hall | Chancellor Hall venue evidence and punk-scene oral-history context. | Context supports the venue's punk role; it is not a substitute for the event record. |
| Buzzcocks / The Slits / John Cooper Clarke | 12 Mar 1978 | Chancellor Hall | Chancellor Hall dossier and late-1970s punk oral histories. | Event record plus scene context; individual source claims remain distinct. |
| Generation X | 9 Oct 1977; 2 Apr 1978 | Chancellor Hall | Two separately documented appearances: 1977 with The Crabs and 1978 with The Jolt. | Do not collapse the two dates; the source-PDF Generation X artefact remains undated. |
| The Undertones | 11 Mar 1979 3 Jun 1979 | Chancellor Hall | Two separate 1979 appearances. March is supported by contemporary Record Mirror; June by surviving ticket and independent listings. | Keep the two dates separate; do not collapse them into one appearance. |
| Dr Feelgood | 7 Nov 1990 | Chancellor Hall | Paul Cleary independently recalls seeing Dr Feelgood at Chancellor Hall in 1974. | Two separate claims: a 1974 oral-history memory and the 1990 event record. Neither is used to “correct” the other. |
| Blue Ramblers | Multiple undated scene references | Odeon / Shire Hall / Lion and Lamb | J. Alliston oral history covers bookings, weekly Odeon dances, Shire Hall, Lion and Lamb and the changing local scene. | Oral-history scene evidence; not converted into a dated event list without separate records. |
