Did You Know? The Chorus to Wagon Wheel was written by Bob Dylan in 1973 and recorded on a demo but was left unfinished as a song. Then 25 years later Old Crow Medicine Show singer Ketch Secor added verses to the song.
Did You Know? John Lennon was unable to release the song (and Rock 'n' Roll the album it was from) because producer Phil Spector disappeared with the master recordings. The record company later had to buy them back for $90,000.
The chord progress in Stand By Me was so common in the 50s and 60s music that it became know as the 'Stand By Me Changes'.
