Bradford's Teddy Boys had turned back the clock 20 years during the summer of 1977, by entertaining the crowds with an open-air concert outside Bradford’s Provincial House. The aim of the gig was to raise money for the Lord Mayor’s Silver Jubilee Appeal. Supplying the beat was local rock ‘n’ roll band 20 Flight Rock and performing in the foreground is William Bentley, then 56 and termed “the grandfather of the Teds.”

To the delight of shoppers who had stopped to watch they revived some of the favourite dances of the 1950s like the solo bop and the catwalk. During the interval the group passed round a hat to collect money for the appeal.
