November 14th 2002 is the 50th anniversary of the first official Top 20 chart; it's also the NME's 50th anniversary. To celebrate these two iconic events in British rock and pop music history, and for the first time ever, the OCC (the Official UK Singles Chart) have produced the definitive list of the UK's favourite singles. This, the official anniversary book, introduces each act and record in turn. With photos and editorial from the NME's unique archives.
