I just remembered another beautiful bluegrass song but I'm not at all sure that that's the title.The chorus was somewhat like this:

          I'm gathering flowers to make a bouquet,
          Beautiful flowers that will never fade away.
          Each one I gather's so precious to me,
          Each one a treasure of sweet memories.

In the ensuing verses, each flower represents a member of the beloved family.I may have heard it sung by The Country Gentlemen" but I'm not sure of that either! Sorry I can't be more specific.
