Gas lighting ignited some gauze backstage on the opening night of a romantic comedy called Romany Rye.
A witness reported:
"Soon after the outbreak the City Fire Brigade were on the spot, but the water they poured on the fire was absolutely without effect."
The number of exits proved to be inadequate for the audience.
Only 68 bodies were recovered.
The blaze led to national fire safety reforms.
There were 800 people in the audience and most of the deaths occurred in the upper gallery.
Victims were buried in a mass grave.
