I've recently been rewatching 6 old UK BBC Bristol TV programmes called "The Train Now Departing" from late 1988.

The opening sequence was a steam train going over a viaduct which morphed into the scene 20 years later minus the railway. The music over this is an absolutely magical piece, played on fiddle(s), acoustic guitar and maybe flute. It sounds rather Dave Swarbrick-y, but the fiddle is perhaps closer to Peter Knight or maybe Aly Bain and I don't recognise the guitarist. The music is credited to "Bare Necessities".

Please, does this jog anybody's memories as to who actually composed and/or performed this? Thanks Mudcatters!
