Back to 1978 we go this week, for the Top 40 of w/e 27th May. Saturday Night Fever was still going strong, and Grease gave us a new entry that was set to be a future No. 1. You'll hear both sides of Boney M's classic single (not officially a double-A side, but both songs were played on the radio), and other popular artists were Darts, David Soul, Blondie, Ian Dury, and look out for some late 70s punk from Plastic Bertrand, The Stranglers, The Boomtown Rats and X-Ray Spex. There's Eurovision entries for the UK (we didn't win) and Israel (they did), and lots more great memories besides.
