The Steve Miller Band performing a fantastic early version of “Fly Like an Eagle” on the Midnight Special in 1974 - two years before the song was officially released.
Gregg Allman performing an acoustic version of Midnight Rider (1991). This song is 50 years old and it’s still as cool as the day it was made.
