I'm looking for the lyrics for the above song. I am unsure of the title, but the opening lyrics of the chorus are:

Do not wait 'til I'm under the clay.
Let your blessings be given today.

I do not have the name of the performers. It sounds like some old-time country music (from before country music was invented) with at least two singers, a guitar, and a tenor banjo.

The theme is to give me the things you might bring to my funeral (words, flowers, etc.), but give them to me before I die, so I can truly appreciate your kind thoughts, etc.
