“The Ultimate Ultimate Greatest Hits Tour,” as England’s Graham Gouldman, 79, calls it, hits the Carteret PAC Sept 13. He’s sold upwards of 30 million records with 10cc, the band he started in 1972. “I’m Not In Love” (1975) and “The Things We Do For Love” (1976) still sound as fresh and vital today as when they were first released. Then there’s “Dreadlock Holiday” from the 1978 movie The Social Network. Gouldman is touring with a whole new 10cc as he switches off between acoustic and electric guitars plus bass amid drums, percussion, keyboards and mandolin.
