There were six versions of Teddy Boy and two of Maggie Mae performed on 24 January.
You can hear the electric guitar in the second part of the Anthology version of Teddy Boy but not on the first part.
The first part on Anthology just seems to be Paul and Ringo playing, with some John harmonies and comments in the background. Then in the 2nd half (from 1:18 on) the electric guitar is there and you can also hear John's acoustic when he carries the song on.
At the end I think John is showing his boredom with the song by doing the "Take your partners, dosey-doh" thing.
There is a different version of Teddy Boy here ...
... which has the "Take your partners" bit at the end but George is messing around over the top of it, and that bit was obviously mixed out on the Anthology version. It goes straight into Two Of Us.
The version of Maggie Mae I posted earlier doesn't seem to include any of the released version - I would assume the released version is the second try at it because on the first one they don't know the words properly and it goes straight into Fancy Me Chances, which isn't the ending on the LIB album. The Let It Be LP version is more "together".
