Newcastle's Mayfair Ballroom was situated in Newgate Street near the North East Co-op on the site that is now occupied by the retail and leisure complex called The Gate. When British pop and rock took wings in the 1960s and beyond it became well-known as a music venue, attracting big acts like Fleetwood Mac, Pink Floyd and Led Zeppelin, but in the 1950s it was one of three regular venues for dance-goers, the others being the old Assembly Rooms and the Oxford Galleries. The Mecca organisation ran the Mayfair. The building was demolished in the late 1990s.
At the time Rose and Peter go to the Mayfair, the craze is for rock 'n' roll. The following video clip, although it's American, shows the typical dancing style. It features the music of Bill Haley and the Comets, who helped start the rock 'n' roll revolution in Britain when they arrived to tour shortly after the success of the film Blackboard Jungle.
