Compay Segundo sang Y Tu Que Has Hecho on the Buena Vista Social Club album. The words are in Spanish, but are beautiful. They don't sound quite so good in English, but go along the lines of:
"On the trunk of a tree, a young girl carved her name, filled with pleasure. The tree, moved to its core, let a flower fall on to the girl.
"I am that tree, moved and sad; you are that girl who wounded my bark. I'll bear for ever your precious name. But you, what have you done with my poor flower?"

Sounds better in Spanish, but you get the idea.
