I had a friend of mine who was not a singer, a musician or a poet, who decided he wanted to perform, reciting the lyrics to folk songs. He recited the lyrics to one of my songs, and it sounded so self-important (how can you make a song about living on the river and frying catfish in a skillet sound important?)that It was difficult not to laugh. Not at him, because he was/probably still is a good man. Most lyrics to songs don't stand alone. I imagine that there are the reverse... poetry that loses something being sung. Just like I feel that there are certain songs that should be sung a capella, because the song is complete in itself and will only be diminished with instrumentation.
