What has happened to 4 people saying" We are gonna play this very old chestnut in D ." and then just launching into the tune? I have played The Red Haired Boy the same way for years. A great guitarist I know showed it to me recently leaving out a chord where I have always put one. The world din't spin backwards. We weren't worried about modes and what was correct. We just played the tune and we had much fun and cheers and Huzzahs! were heard by all.

The point is play the song or the tune and sort it out. Worry about the rightness or wrongness of what you have done when you are doing the doctoral disertation on Traditional Cross Over Tunes of The British Isles and The Outer Banks.

There is no right or wrong there is music and thats enough.
