The Grateful Dead did this twice in 1988, sticking closely to the Beatles' version. Bob Weir has played it frequently with Ratdog and with Weir/Wasserman, as well as with The Dead.
Blackbird singing in the dead of night
Take these broken wings and learn to fly
All your life
You were only waiting for this moment to arise
Blackbird singing in the dead of night
Take these sunken eyes and learn to see
All your life
You were only waiting for this moment to be free
Blackbird fly, blackbird fly
Into the light of the dark black night
Blackbird fly, blackbird fly
Into the light of the dark black night
Blackbird singing in the dead of night
Take these broken wings and learn to fly
All your life
You were only waiting for this moment to arise
Blackbird singing in the dead of night
Take these sunken eyes and learn to see
All your life
You were only waiting for this moment to be free
You were only waiting for this moment to be free
You were only waiting for this moment to be free
