More one hit wonders!

Sometimes a band gets together,  crafts the perfect catchy tune and rises the charts to the top, and then disappears as suddenly as they seemed to arrive. Other bands work their craft for years, pleasing a small and perhaps local audience, and then happen to hitch a ride on the zeitgeist with a single track and never manage it again. These tracks are one hit wonders, and some of them are really very good indeed. This week Marty and Venetia explore some more chart toppers from the Seventies, from acts that hit the big time for one bright, beautiful moment only to fade back into relative obscurity.
