A comment from someone inside the pub at the time...
Grace MacLean was inside the bar at the time of the crash, and said there was no big bang or explosion at first, and just some smoke.
She said: “The band were laughing and we were all joking that the band had made the roof come down.
"They carried on playing and then it started to come down more and someone started screaming and then the whole pub just filled with dust. You couldn't see anything, you couldn't breathe.
Maybe a "Weegie" can answer this. Was the pub formerly known as the Clutha Vaults? I seem to remember it from years ago when staying at the Holiday Inn across the street
