I think Ruth is partly right about Rambling Syd being a comment on material being produced with a trad. music base...although at that time although Bob Copper was involved in broadcasts he never made programmes per se. unlike MacColl, Kennedy, Lloyd and co. Bob always said that it was a lot to do with the BBCs inspired decision to instigate the collecting programme with himself, Peter Kennedy, Seamus Ennis and others and their being in and around BH and meeting regularly to present their latest 'finds'. There were many 'smell of the country' and much imaginary scraping of boots jokes by the likes of Gilbert Harding whenever the 'collectors' walked into one of the BBC pubs like The George or The Stag - so it was well discussed around the Corporation. This was rich material for people like the writer Barry Took and too good to miss for a regular slot on 'Round the Horne'. Polari too would have been quite common currency for those in the know at that time in London.
