There's a lute intabulation of the song Bianco fiore by Cesar Negri that Karl Scheit transcribed for guitar. It's published by Universal Edition and appears in more than one of their anthologies. I'm not aware of a version by VG. Also not by VG is Se io m'accorgo (Anon) which also appears in several anthologies (including International Anthology by Alexander Bellow - Franco Columbo Publications; googling the title also leads to the possibility that there's a Noad arrangement of it, but I haven't seen it.) The Bellow anthology also contains a couple of pieces that are by VG, but not the one's you want which have such non specific tiles that they are not readily identifiable. I guess if you found a facsimile of 'Il Fronimo, Dialogo' (1569) in which VG pulished his work you'd find several pieces with those titles.
