Everyone seems to be aggreeing with everyone for once! I think one question that hasn't been asked is "good for what?" Trained tenors and the like are said to have "good" voices but it's often impossible to hear what they are singing about and the yardstick here appears to be ability to perform vocal gymnastics. Not "good" for folk singing and especially ballad singing: OK for opera where it doesn't matter as the words are often Italian or banal or both! Lead Belly would not make a good long ballad singer either but is unbeatable in his own music. Paul Clayton was a good ballad singer as his diction is so clear; but his voice may be too colourless for some tastes. Richard Dyer Bennet? Not rough enough for me. I find Woody Guthrie just about right - listen to his "Harriet Tubman" - long but not tedious. Frankie Armstrong is said by almost everybody to be an outstanding ballad singer but I can well do without the drama. I think Cisco Houston and Isla StClair probably have the right balance for most listeners. Dr John
