Just out of boredom/curiosity, I looked up a few of these on Youtube...Ken, Joyce, & the Armless Wonder are all pretty much standard issue Gospel/Jesus freak warblers. Heino, altho you might THINK he'd have a high, squeaky, tinny voice, actually has a deep, booming bass voice, & has a LOT of hits in Germany w/the Geritol set. He suffers from Graves' Disease, hyperthyroidism, which affects his eyes & causes him to wear dark sunglasses. Devastatin' Dave, The Turntable Slave, was an anti-drug crusader, whose 15 minutes of fame c.1982 were mercifully cut short to 7.5...
