Thank you Derek and Vincent for your replies. I've been able to watch it at the link you posted Vincent but my download attempts have all crashed so far - still trying! It's a blast from the past for me, I seem always to have known the arias. Thank you for the steer to Amazon, Derek. They don't seem to be posting to Australia at the moment but I will try later if necessary.
For the benefit(?) of anyone else reading this thread, the cheap DVD copies of That Midnight Kiss/Toast of New Orleans and The Seven Hills of Rome that I purchased are absolutely fine quality-wise. There's also an acceptable full version of For the First Time on Youtube.
Derek, I just wanted to thank you for the discography and disk reviews on the website, they're a great resource.
regards
Verna
