I remember the Hansel and Gretel conversations quite well (but ... three years ago???). I was only lamenting that I'd never picked up any of the CDs. I'll order the Moffo forthwith, and perhaps the Schwarzkopf. I do have the classic 1950s MET recording with Rise Stevens on LP. Has any of that series ever made it to CD, I wonder?
Would it be a worthwhile project to restore that stop-motion film? I've only looked at it once on that dismal DVD.
I'll eventually check out others, but my go-to DVD remains the MET telecast with Judith Blegen, Frederica von Stade, and Rosalind Elias.
