This is an old hymn whose tune I always loved, but no one ever sings anymore. I suppose it's not surprising - the first line is "There is a fountain filled with blood drawn from Emmanual's veins." Catchy tune, but the lyrics are a little....creepy."
I always loved the tune, though, and it's in the public domain. Why not? It's short and sweet - just 1 minute of appalacian acoustic folk.
