Hi Again,
Here is a theory as to why the guitar solos are different, if you listen to the DVD-Audio mix of Never Going Back Again, over the acoustic guitar solo there is an electric solo that occurs about half way through.
Again remember that this is just a theory but what if they used the acoustic solo as a base for the electric solo, and extended/repeated it to allow for the electric to finish, however since the electric solo didn’t make the final LP mix they may have just kept the acoustic the way it was.
Then they went back to gather tracks for the Chain used an updated version that didn’t include the repeat as it was not necessary?
Just a thought.
Take care
