Sounds like a modified version of a Christian song with these lyrics:
Lyrics
First version
Jesus, Jesus,
Can I tell you how I feel?
You have given me Your spirit.
I love You so.
Second version
Jesus, Jesus,
Can I tell you what I know?
You have given me Your spirit.
I love You so.
No, I have had no response until you right now. I too discovered nothing online. The story was told to me I believe when the song was sung at a closing campfire at an event in the seventies I think, in the old Great Western Council. The words I recall were varied, though that could be my old mind. "America, America. How can we/I tell you how we/I feel? You have brought us so many treasures. We love you so. A second stanza, or just version, replaces treasures with pleasures. Simple and very meaningful, especially if it was sung on the tarmac as American scouts left a Japanese gathering of some sort. I do know that the BSA was involved in reestablishing Scouting in Japan, so it might relate to that, rather than a Jambo. Or it might simply be "lore".
Word on the internet is that Bucktail just had their charter revoked and they are being absorbed by Laurel Highlands. When I looked this one up I was confused as to how a council the size of a district (in my council) even existed in the first place.
