Levon's description of her:
"Our...favorite act was 'The Lady with the Million Dollar Smile,' F. S. Walcott's big featured singer, who'd come on in the third quarter of the show. She was an armful. She wore bright dresses and had all her teeth filled with diamonds! She sang on all those real get-down songs like 'Shake a Hand'."
