I found this but the spelmanslag calendar has events for Sept and November, not Oct -- may be worthwhile enquiring
http://www.spellmenn.no/ (or may be of interest to other mudcatters travelling at another time)

I will of course be doing other things, trip wasnt planned as a music excursion but that could be icing on the cake

I remember at least two Mudcatters of the past who lived in Norway, one of them lived near Voss and studied in Ireland- she was a singer/student of folksong
