The sources disagree on the night.
No Venue's Website or social account could be found for Bar 404 (checked Aug 31, 2026). The only source is an open-mic listing site, which describes the jam as running the 2nd and 4th Tuesday, with blues given priority but all welcome [s1]. That description is specific but single-sourced, with no venue-owned corroboration.
