Highway to Hell

This knocked me out with those suomalainen whys?
We are at an AC/DC marathon. The location is perfect, for as anyone should know, Oulu is the home of the annual Air Guitar World Championships, and as anyone who knows anything of the noble art of shredding and air guitarism, many many AC/DC tunes rank high on the list of favourites... A group of Finnish tribute bands and one imported all the way from America are playing their way through the entire output of AC/DC, one album at a time. This is a first in Finland, perhaps even a world première.
