Not sold as that AIUI. Cambridge to Zones 1 & 2 Saver Return: 29.00,

Interesting. I thought that at least prior to the 2006 fares revision,
you didn't get the Railcard discount on the U12 part of the fare. (The
through fare would have been calculated as the sum of a Cambridge to
Finsbury Park Saver Return plus two Z12 Tube fares. Now, it's done
differently, though I'm not sure how.)
