English: Up Helly Aa (7) - the Burning Galley
Once the galley has burned and the flames die down, a night of partying begins. Any available large room is pressed into service as a hall, presided over by a hostess who issues invitations to attend, and every guiser squad visits every hall in turn to dance and drink with the guests.
As there can be dozens of squads and dozens of halls, this takes most of the night and well into the following morning. On the Wednesday, the only thing which moves in Lerwick is the 'hangover bus' taking passengers to the airport at Sumburgh.
