'Song of Norway' has been a bit of a dog for me, and a bit too "ghosty".. I may try it in a different spot to see if it performs any better... but after several years, it's so far failed to impress me.
I haven't seen 'Elizabeth Poldark' before... she's lovely! I've heard that 'Vanity' is a better grower than 'Beverly Sills', which has been a little slow for me.. Someday I'll get one to find out....
