My friend one day came to me with a cartoon from guitar player magazine that showed a bum on the streets playing a guitar. The guy walking by was supposedly a Guitar institute student whose caption read " Who's that butchering those chords ?', Finalizing the piece was the statement. Know your teachers.
As a songwriter I've had some success but I can't play a clean chord, nobody wants to be in a band with me and I can't sing, but write I do. Thus, I'm The Song Butcher. So there ya go.
