Johnny B. Goode Master equals take 3

In June 2008, there was heated discussion by commenters of this blog regarding Two Guitars on Johnny B. Goode. One thing not discussed then was the differences between the known recording takes.
Reader Dennis had some more listening and found out:

While listening to the various tracks on the 4CD set I noticed that take 3 of the alt. take JBG 2/3 and the final master on Chess 1691 are the exact same recording. It's just one version without and the other with the overdubs. This can be heard quite clearly by listening to the improvised piano fills which are completely identical. Within the discussion it was not made clear that you were talking about the same recording in two states of finalization.

Fred and I spent some more time listening to the tracks and we can confirm Dennis's findings. Thanks for this additional information.
