OK, thanks to everyone's suggestions I ended up ordering the following:

Respighi, Roman Festivals,et al, Dutoit with the Montreal Symphony, London LON 410 145 as recommended by JohnK

Holst-The Planets; Fantasia 2000; and the Nutcracker ballet by George Balanchine/New York City Ballet; all recommended by Sushi (with very helpful links).

Now I patiently wait for them to arrive and I think that should get me started.

PS - Are there really no Norah Jones fans here at all? OK, I know it's not classical, but she did win 7 Grammy’s and I think classical fans would enjoy the change of pace. Very soothing voice.
