My Dream Duets, by Barry & Various Artists (as the Grammy website put it) IS a nominee in the usual category--Best Traditional Pop Vocal Album.
The other nominees in the category are:
The Silver Lining: The Songs of Jerome Kern--Tony Bennett & Bill Charlap Shadows in the Night--Bob Dylan
Stages--Josh Groban
No One Ever Tells You--Seth MacFarlane

It'll probably go to Tony Bennett, as usual. I wouldn't mind if it went to Josh, though. My local PBS station aired a concert based on the Stages CD this past Friday night & I really enjoyed it. I haven't heard the Dylan CD, so I can't comment on it.
Also... I've gotta say, Seth MacFarlane is a surprisingly good singer--not like you'd think based on the other stuff he's known for, like "Family Guy". I watched the "Sinatra 100" special the Grammys produced, to mark the upcoming 100th anniversary of Frank Sinatra's birth, which was on CBS last night. Seth was the host, & he also sang at least a couple of solos (I remember 2)--1 was as part of a group, as I remember, & the other was a legitimate solo. He acquitted himself very well, vocally.
