As the longest-running children's show in TV history, Blue Peter has been a cultural touchstone and rites of passage for youngsters in Britain for as long as any of us can remember.
Imagine the excitement then in 1973 - when the iconic BBC show was at the peak of its powers - when Blue Peter ventured north of the border to capture the best of the city's sights and attractions during the Edinburgh Festival.
Reporting from Auld Reekie that August was legendary Blue Peter presenter Valerie Singleton, who still filmed special assignments for the show despite no longer being a regular host since 1972.

During the half-hour special assignment, Valerie visits the Scottish crown jewels at Edinburgh Castle, witnesses a demonstration of the One o'clock gun, meets the penguins at Edinburgh Zoo, and tells stories of famous city heroes and villains such as Greyfriars Bobby and Burke and Hare.
Val even takes a trip to the Thirty Seven Bar in Rose Street, where she speaks to publican George Robertson and is amazed to discover the dozens of whiskies the famous pub has available.

Asked by Val if it's true that Scotsmen really do drink as much whisky as it's claimed, Mr Robertson replies: "Oh yes, they do - that's the wine of the country!"
We're also treated to a glimpse of Fringe performers on the Royal Mile, which Valerie describes as "trendy, youthful, experimental and often disrespectful".
Our personal favourite part of the special, however, turns up at the 11-minute mark when Val stops off at Bruntsfield Links for an endearing chat with a group of youngsters playing pitch and putt.
After explaining that the game of golf has been played on the compact 18-hole course for generations, Val chats with a few of the kids, who are on great form.
We'd love to hear from anyone who recognises one of the young faces featured in the clip - so please let us know in the comments section below.
