I don't know if this would fit, and I don't know where you'd find the tune, but we used to do a song in our church teen choir back in the '60s ... Judas and Mary (sung as a duet):

Said Judas to Mary, "Oh, what will you do
With your ointments so rich and so rare?"
"I'll pour them all over the feet of my Lord
And I'll wipe them away with my hair," she said.
"I'll wipe them away with my hair."

"Oh, Mary, Oh Mary, oh, think of the poor
This ointment, it could have been sold.
And think of the blankets, and think of the bread
You could buy with the silver and gold," he said.
"You could buy with the silver and gold."

"Tomorrow, tomorrow, I'll think of the poor,
Tomorrow," she said, "not today
For dearer than all of the poor of the world
Is my love who is going away," she said.
"My love who is going away."

Said Jesus to Mary, "Your love is so dear
Today you may do as you will.
Tomorrow, you say, I am going away
But my body I leave with you still," he said
"My body I leave with you still."

"The poor of the world are my body," he said,
"To the end of the world they will be
And any kind deed that you do for the poor
In truth you are doing for me," he said
"In truth you are doing for me."

I think I've remembered if fairly correctly. I always loved that one!
