Art Garfunkel says he is in good voice as the 40th anniversary of Simon and Garfunkel’s classic album “Bridge Over Troubled Water” approaches. “Bridge” came out in 1970 just before he and Paul Simon parted ways, but Garfunkel still performs some of the duo’s hits on tour, and he is planning to start recording the material again. “I’m going into the studio on Monday with my guitar-player friend, and I’m … going to do some Simon and Garfunkel stuff, stuff I do on my solo tour,” Garfunkel told the New York Post. “I’ll work the baritone and the tenor and see if it is as encouraging on the microphone as when I walk and sing,” he added.
