Will the Circle Be Unbroken?
The Nitty Gritty Dirt Band made the original Will The Circle Be Unbroken collaborative album in 1972. The album included an all-star performance of the song "Will The Circle Be Unbroken." This you already have listed.
The Nitty Gritty Dirt Band made another such album in 1989, called Will The Circle Be Unbroken Volume 2. This edition also included a cast of dozens performing the song "Will The Circle Be Unbroken." This one you also already have listed.
The Nitty Gritty Dirt Band went back to the well in 2002 and made Will The Circle Be Unbroken Volume 3. Once again, the album featured a recording of the song "Will The Circle Be Unbroken." This one I did not see listed.
I see enormous potential for confusion between the three versions. Thus I humbly submit this transcription of the credits from the liner notes of Circle 2 (as it is known), the 1989 album. (I couldn't get hold of Circle 1 or 3 today.)
