Thanks. the big problem here is that my rubber duckie can't sing along in all of these minor and diminished chords. Plus, we sometimes sing it under water in the tubbie, and I have trouble getting these tough guitar chords right under water. For the typical semi-literate, guitar player, what would work in major chords and 7th chords. I want to teach this to lots of kids, and the chords have to be simple. AND, PLEASE!!!!! Don't anyone tell my little know-it-all grandson that his grandpappy whodo was wrong on this.
