IT'S BEEN A LONG time coming, but I think the pop revival is finally upon us. This "pop revival" has been somewhat hyped in the press, and is most visible in its English exponents like Slade, and T. Rex and to a lesser extent, acts like David Bowie, Roxy Music, 10 CC, and Wizzard, Here in the U.S., the exponents have not been, so. publicly extolled, but they can be found among the ranks of such as Raspberries, Pagliaro, Big Star, Curt Boetcher, Stories and Sparks. But perhaps the group with the greatest potential, and best understanding of the pop-genre is the Sweet.
