also there will be streaming video of the event from 4pm on Up Helly Aa Day, Tuesday 25th assuming there is enough bandwidth available. The torchlit procession starts at 7.30pm, the light-up of the torches is spectacular.
I'm going to be in Shetland for it this year, so I hope to go and have a look. Heard many a story, but it basically sounds like a 24 hour drinking session during which a longboat gets burnt. There is a lot more to it than that but outwardly that's is what it seems to a Soothmoother (local term for anyone who has the temerity to come from any where south of Fair Isle)
