We had a fire alarm go off at the Assembly Rooms in Edinburgh - mid-November, cold and wet outside, during the Fiddle festival.
We were 99% sure it was the caterers burning the toast that set it off, but everyone was evacuated as per orders, reluctantly leaving their precious fiddles to (maybe) burn. (and it took some severe persuasion with some folk to get them out!)
While outside, it was suggested the following tunes should be played on re-entry:
The Burning of the Piper's Hut
Smith's a Gallant Fireman, and
The Peat Fire Flame!
