So, Ray got started in radio, not as a DJ but by recording his early singles at radio station studios. In Atlanta, Chicago and New Orleans.
The classic "Rays Blues" was recorded at WDSU-AM in New Orleans in 1953 as were many other sides. I got a woman was actually recorded at WGST-AM in Atlanta (still owned by Georgia Tech at the time, ...and 4 sides were put to tape WMAQ-AM Miami.
It was Zenas Sears, then only an Atlanta deejay , got studio them time for on WGST they recorded some of his all-time classics including I've Got A Woman, Greenbacks, Come Back Baby, and Blackjack. The only reason Ray was in the WDSU studio is that Cosimo's was booked. He still managed to lay down a killer version of Don't You Know with a backing band of hired hands.
