IvanB- You have a first edition- Celebration of Life was first published by Big3...

The second edition was done through Oak Publications and holds up very well...we took out some of the big black spaces and took out one or two songs, added a few others- that's when, "Early Fields" got in. We're now working on a revision ourselves (Geordie Music Publishing Co.) making it yet a bit more tailored... Best to all, Jean "

My copy is published by Geordie Music Publishing. I need to look for one published by Oak Publications.
