The concept for the Roadshow came from Radio 1 producer and later controller, Johnny Beerling and was envisaged and purchased by Tony Miles, built and maintained by John Dean, with engineers Peter Lucken and Johnny Heritage. The first Roadshow was held at North Fistial Beach Newquay, Cornwall, on Monday 23 July 1973, and was hosted by Alan Freeman.
Various disc jockeys from the station would visit British towns, usually on the coast, to play a live set, meet local people to play their requests, take part in games and give away "goodie bags" of Radio 1 gifts. Accompanying the DJs were the support crew, led by Tony Miles, nicknamed "Smiley Miley", who had provided the original caravan for the first Roadshow.
Several games were devised especially for participation in by the live audience. Most notable were two that ran throughout the Roadshow's history, 'Bits and Pieces' and 'Smiley Miley's Mileage Game'.
