Opportunity Knocks (2)

The Thames talent contest Opportunity Knocks ran from 1956 to 1977, with the first 12 years on ABC. The granddaddy of talent shows, outlived by ATV's New Faces and more recently superceded by the likes of Pop Stars and The X Factor, Opportunity Knocks brought us a whole wealth of talent: Bonnie Langford, Bobby Crush, Peters and Lee and Lena Zavaroni. It also provided auditions for Les Dawson, Freddie Starr and Mary Hopkin. This 1971 All Winners edition features a big surprise for Dawson, when he is surprised by Eamonn Andrews and made the subject of This is Your Life!
