Noel Edmonds turns back the TV clock for a nostalgia quiz looking at the events and trends of a bygone year. Tonight features 1972, when Noddy Holder topped the charts with Slade, pentathlete Mary Peters won Olympic gold, Cyril Smith became the Liberal MP for Rochdale and Lynsey de Paul wrote and sang her first hit, "Sugar Me". They join Noel to be questioned on the top stories of the year they found fame.
