Ever since I made the life changing decision to attend an ABF rally, I've wondered about this piece.
It was one of the first "group numbers" I learned (along with "Sunflower Dance/With the Tide" and WF).
There are three circulating arrangements, the CE published Burt Earle "arrangement", the one from the Bradbury method (I play this one) and a manuscript from Alex Magee.
Since I am a nerd, I've tried to track down an original copy to see if and how it is different than what we are playing now, and if Gregory was the actual composer.
Well, here it is.
What is fascinating is that, along with the A notation, it was also published in the "simplified version" or the Henry Dobson "open and shut" method.
Pretty cool I think.
