Antiques Roadshow is a British television show in which antiques appraisers travel to various regions of the United Kingdom (and occasionally in other countries) to appraise antiques brought in by local people.
It has been running since 1979, based on a 1977 documentary series.
The series began as a 1977 BBC documentary about a London auction house doing a tour of the West Country in England.
The pilot roadshow was recorded in Hereford on presented by contributor Bruce Parker, a presenter of news/current affairs program Nationwide and antiques expert Arthur Negus, who had previously worked on a similarly-themed show, Going for a Song.The pilot was so successful that it was transmitted and the format has remained almost unchanged ever since. In the original BBC series, various towns or famous places are advertised as venues.The original theme music was Bach's Brandenburg Concerto No 3 (for several years in a Moog synthesiser version by Walter Carlos), but was changed in the early 1990s to an original piece, by Paul Reade and Tim Gibson, which has been used ever since.The Antiques Roadshow will be holding a Valuation Day at Scone Palace.The show's presenter, Fiona Bruce will be here along with the team of experts, so why not bring along your family heirlooms or car boot bargain and find out a little more about them, you never know they might be worth more than you think!Fiona Bruce introduces the finds that stood out in terms of pure quality from 31 years of Antiques Roadshow valuations, and we meet the mystery owner of a 100,000 pound piece of furniture.
