The most widely played version on radio, in the 1960's, was that of the Limeliters. Glenn Yarbrough sang it, virtually, as a solo and may have recorded it on one of his own records as well. It begins in a minor (I used A minor) and progresses to D major.

         Am
I do not have a mansion, I haven't any land,

Not even a paper dollar to crinkle in my hand.

But I can show you morning on a thousand hills,

And kiss you and give you seven daffodils.
