The Gresford Disaster.

John Tams, formly of The Albion Band, did the research into the song, and found that it had been written in the form of the great, black-lettered, broadside ballads to raise funds for those who had been
widowed and orphaned by the accident He also discovered that the colliery band was at the pithead as the bodies were being brought out, playing to try and raise the spirits
of the wives, children and friends who were waiting. One tune the colliery band is known to have played, according to Tams, was How Sweet the Name of Jesus Sounds (in a believer's ear)

I've no reason to believe that John Tams is in anyway mistaken.
