To put that in proper context, Bob Harris has been around the sun a fair few times and in the top echelons of new and independent music discovery for a very long time too: 'The Old Grey Whistle Test' with Bob presenting ended decades ago (it ran thus from 1971-1978). In that sense he has been there since the start of my music experiences. I still remember seeing bits of that as a child. Since then he has become something of a lodestar for those interested in roots and acoustic music beyond simply UK and Irish folk and through most of those decades it wasn't a part of mainstream musical fashion, to say the least. How times have changed!
Here is the video for that song too:
