This fakebook style arrangement is not a 'solo' per se.
It is the melody with ALL lyrics supported by Banjo Accompaniment in the key of G.
The banjo plays arpeggios of the chords (one note at a time) all the way through the entire tune.
The slow nature of this great Jon Allen song made it better choice for the banjo acting in accompaniment mode only.
Having said that, the chords run all over the neck... so even as a slow tune... it may require you to learn chord forms higher on the neck. Not a bad thing... There is always more to learn!
After working this arrangement out, I have become a Jon Allen fan.
Thanks to Graham from the BHO for this great suggestion!
