A similar story is handed around where I live. There was an accordion master, dead now, that started out as a failure roaming the land and looking for a teacher. He would often stop to check himself into an Inn run by a fellow named Matthias Åkerfeldt. Not much is known, but eventually the mysterious proprietor sat and had a drink or two with the accordion player. Overnight, he went from would-be pupil to master.
We don't know exactly what happened, but it's got something to do with the Åkerfeldt family. The truth is out there.
