This is a Mike Harman transcription. He played with Alison Krauss in her early years and played banjo on this track from her Two Highways album. This arrangement of Wild Bill Jones is mostly Scruggs, but there is one melodic lick in measure 6. At measure 9 he's already played through the tune, and most people end there, but notice how he hammers on that 7th note right up until the following measure. That's where the vocals start, that rhythmic and melodic emphasis helps drive the song and energy, and makes for a smooth and exciting transition from banjo back to vocals.
