One day in 1946, twenty-one-year-old Riley King, of lndianola, Mississippi caught a ride on a grocery truck all the way to Memphis, about 140 miles north.

If you had a quarter, you could get a good meal that would last you all day at a place called the One Minute Café. Fifteen cents’ worth of chili, nickel’s worth of crackers, and the boys made a drink with different flavors, orange, grape, and so on, and you’d get one of those, we called it bellywasher. That would be your meal for a whole day, for a quarter — at a time when I didn’t have many quarters, you can bet on that.

They had three theaters on Beale, the New Daisy, the Old Daisy, and the Palace. The Palace was where you went to hear the people I just mentioned, the elite in music. The Palace also had the amateur show every Wednesday night, where Rufus Thomas was emcee. I went on it every chance I could. I never won. Never. Then there was
