Gallagher's band at the time was Gerry McAvoy on bass guitar, Lou Martin on keyboards and Rod de'Ath on drums.

He originally planned to use the footage for a television special, but he later found it so good that he released it as a theatrical motion picture.

Violence from Irish Republican Army and Loyalists was erupting throughout the region at public events such as rock concerts.

A local Belfast journalist writing to describe the concert said: "I've never seen anything quite so wonderful, so stirring, so uplifting, so joyous as when Gallagher and the band walked on stage.

The whole place erupted, they all stood and they cheered and they yelled, and screamed, and they put their arms up, and they embraced.

Rising up in volume eventually over powering the waves is the sound of Gallagher's guitar as he leads into the first song Walk on Hot Coals.

For the next song, a traditional blues number Goin' to My Home Town Gallagher performs mostly on his own with a mandolin.
