There were several Shadows in every country, as we - of a certain age - all know. The biggest bands in that vein in Sweden was The Violents, The Spotnics, and The Shanes. Though the big difference between the first two, and the last, was that The Shanes wrote their one tunes. The popular way to find material was to take folk tunes, put a twist beat to it, a boogie bass in the bottom, and a guitarist that didn't look away from playing the melody part, some verses in the lower register, some in the upper, and then - to increase the tension - played the melody with the pic hands palm muted over the bridge.
The Shanes concentrated on their own material.
And, yes, they were from Lapland. My county.
