The story is about choir practice at a church.
A few other details. There had never before been a choir practice where all members were late.They were due at 7:20, but most were usually there by 7:15. Often co-incidences that can seem uncanny are in fact urban Myths.
Those who can verify the co-incidence, include the members of the choir, and the fire department.
It is suspected the explosion was the result of a gas leaka gas leak.

<The Roots of Coincidence, written by Arthur Koestler, is an accessible introduction to theories of parapsychology, including extra-sensory perception and psychokinesis. It postulates links between elements of quantum mechanics, such as the behaviour of neutrinos and their interaction with time, and these paranormal phenomena. It is influenced by Carl Jung's concept of synchronicity>

There is a Dept of Paranormal research at Edinburgh University which is based on Koestler. Some years ago, I read a book outlining stuff on coincidence and the Edinburgh ubit by, i think, Brian Inglis.

Yes, co-incidence. Events in my life were most extraordinary at the time. Later evidence proved they were co-incidence.
