This is the second tune from The Portland Collection folks set
Shamrocks in the Galax/Damon’s Winder/Two Wide Nickels
I contacted one the members (Sue Songer) about composer/permission to post to which she replied:
"I do know about those tunes and am so glad you like them well enough to learn them and disseminate them. Damon’s Winder and Two wide Nickels are both in the public domain." - nice lady, eh?
They have a great website with lots of handy info
I could find no other source on the net so wrote them out as best I could and placed them here.
