Zoney, that's the function of Categories.

Ah, but you see, that's exactly the kind of thing that would be nice to stop (in my opinion). If for example, [[Gilbert O'Sullivan]] is likely to be confused with [[Gilbert and Sullivan]] (and I'm not certain about that, but yes, there are other plausible examples), it should surely be treated as disambiguation, not lumped in with a list of *related* articles. "See also" is too much of a "catch all" title.
