The grinning entertainer, who sold over 45-million records, died Tuesday morning in Nashville.

Campbell was everywhere in the late 1960s and well into the 1970s.

He won five Grammys, had a dozen gold albums and 75 chart hits, including ‘Southern Nights,’ and ‘Rhinestone Cowboy,’ which went to the top in 1975.

In his autobiography, ‘Rhinestone Cowboy,’ Campbell wrote ”I thought it was my autobiography set to song.”
