A song I heard last week* has been going round in my head ever since, despite the fact that I can't remember a word of it. A lovely song (beautifully sung), but what was it?

I can't help with the words, but the tune goes something like this (I'm not 100% sure of the second half of the third line):

X:1
M:4/4
K:D
L:1/8
B2|A3 ddc A2|e2 ef g2 fe|d2 ed cAAG|A6 B2
|A3 ddc A2|e2 ef g2 fe|d2 ed cAAG|A6 f2
|g2 e2 a2 d2|cdef e3 e|d2 ed cAAG|A6 B2
|A3 ddc A2|e2 ef g2 fe|d2 ed cAAG|A6 f2||

Anyone?
