Ok, tags work with music, not with books.  Here is what I would suggest:

ConcertBook =
\book {
  ...
}

and then you can at a later point of time say

\ConcertBook

and can comment that line out or not.  Assigning #f to ConcertBook when
a command line option is set is a bit trickier, but still reasonably
easy.
