I assumed Rucker wrote it.Rather embarrassing for someone who claims to be an above above average Dylan fan. I had no idea that he wrote the chorus for this in 1973.
From the Wiki: "Wagon Wheel" is a song co-written by Bob Dylan and Ketch Secor of Old Crow Medicine Show. Dylan recorded the chorus in 1973; Secor added verses 25 years later.I assumed Rucker wrote it.
That's my serenity song...WW trifecta complete.
