The bluegrass standard ‘Fox On the Run’ “… (was) written by Tony Hazzard in 1968,” (Bluegrass Today) ” … Having been raised in the country on the outskirts of Liverpool as a young boy, Tony had a lot of inspiration to draw from for the imagery in the song. ‘The main source was an imagined scene, described in the chorus, of a hot summer’s day, a field of wheat sloping down to a river in the sunshine, and a blonde woman walking through the wheat field towards the river … The second source was really just the feel of the music. I was a fan of The Band in the late 60s, and their style was running through me at the time.’
… Tony played the song for British rockers Manfred Mann’s Earth Band and in 1968, ‘Fox on the Run’ became a hit song for them in the UK … In 1976, Tom T. Hall took ‘Fox On the Run’ to #9 on the US Billboard Charts and to #12 in Canada. The song went on to be recorded many more times by bluegrass and country bands all over the US. You can hardly walk past a festival jam without hearing a version of this beloved chestnut … (Tony adds) ‘I eventually realized it had become a standard, and I’m very proud of that fact; the song will remain long after I’m gone, and if people think it’s an old folk song, that’s fine by me!’”

For good measure, here’s an example of the tune’s frequent setting in the Bluegrass genre, as represented by Bolt Hill Band:
