Eggs Up - The Alternate Back To The Egg
(vinyl bootleg - remastered)
This was originally posted by one joesjoint to the lossless Usenet group (thank you very much!). From the original poster's notes:
Remastered from Vinyl in professional recording studio
this particular remaster sounds a little bit better than the one on Masterfraction's 2CD release.
This is the rough assembly prepared for "Back To The Egg" in early 1979, after work was completed on the recording & overdubbing in April of 1979 (see Madinger - Easter p. 241 for more details).
