by Bill DahlFrederick Knight's catchy "I've Been Lonely for So Long" was a sizable R&B hit on Stax in 1972, and he wrote and produced Anita Ward's across-the-board smash "Ring My Bell" in 1979. Knight cut his own "I've Been Lonely for So Long" in Birmingham, Alabama with a seasoned southern soul crew behind him, and hit again in 1975 with "I Betcha Didn't Know That."
