This page:http://imslp.org/wiki/Quel_fior_all%27a ... e_Frideric
may have a wrong HWV number. Grove Music lists 4 versions of this, each with its own HWV number. They say that HWV 192 was 2 sopranos only, and that HWV 200 was the version for 2 sopranos and continuo. (There is also a solo cantata HWV 154 and then a version with a slightly different text which doesn't seem to have an HWV number).
However, this specific page, since it has continuo, would seem to be HWV 200. It's a typeset, with no source listed.
Should I just move it?
(I'm holding off tagging it until this is resolved.)
