I'm older than you. One time when I was a little kid our parents bought the first color tv on the block, sometime in the early 50s. Most television programming was still live. One eveing the country singer Jimmy Dean was on, and when he opened his mouth to sing, there was green dye all over his tongue from Clorets.
Lol! I remember hearing about a live performance by opera singer Beverly Sills where when she opened her mouth to belt out a big note she inhaled a moth.
