Hallmark Commercial

I watched The Water is Wide on CBS tonight. It was a Hallmark movie, so nearly all the commericla breaks were Hallmark card commercials--I cried a lot. Anyway, one of the first commercials was about an older man going to see a teacher every night so he could learn to read. The background song was amazing,and I would love to know the name of the song and the artist. Any ideas? Some of the lyrics, I think, were, "...your love is my salvation..." and it did have a bit of a Nick Drake feel to it. Help!!
