I can't work out the behaviour of this page:
http://imslp.org/wiki/Quintet_(Pepusch, ... hristopher)
It has no tags, but it doesn't say "unknown tag", nor does the work come up on the untagged list.
I've added a comment about tagging, since I think it will need a name change, but in the meantime, I need to at least ensure that it will come up on the untagged list, otherwise it will disappear into the ether . . .
