Ray Charles made a career from adapting religious songs. "I Got a Woman, Way 'Cross Town" is from "We Are Crossing Jordan's River, I Want My Crown".
Nat "King" Cole sang "Answer Me, Oh My Love" after Frankie Laine had recorded the original "Answer Me, Lord, Above"
The 50's was a time of such adaprions. I will never forget Patti Page covering the Jewish Prayer "Eli, Eli" as "Father, Father". At least Perry Como sang it in Hebrew.
