pity David Attenborough didn't know the difference between Ewan MacColl and Ian Campbell, he went on about Ewans voice etc, the played Ian singing ' The Shoals of Herring ' and again later said it was Ewan.

Don't necessarily blame Attenborough for that, Having recorded his script, the musical extracts will have been edited in later, either by the producer or by a technician. DA may not even have heard the final product before it was broadcast.
