What are the odds of an Erik Pettersson and a Petter Eriksson being in the same band? I'm being serious, Stefan. Are those common name combinations?
In Sweden it is. Strange country...
More examples: Andersson, Svensson, Johansson, Gabrielsson, Hansson, Karlsson, Mikaelsson, Jansson, Melkersson...the list goes on and on and on....
