Old Joe is really fun to play on the fiddle in cross tuning in key of a AEAE. I've recorded a version on banjo in the key of G (can't sing in A for the life of me)and interestingly enough, it is fairly easy to play one of the parts way up the neck in a higher octave in standard g tuning - very cool. Joe Clark by the way is looking to be the next Prime Minister of Canada.
