I watched the first 3/4 of "The Sound of Music" last night before having to switch over to a PBS showing of part two of a Masterpiece Theater classic starring Helen Mirren as "chief inspector"/"chief detective"/"detective superintendent" - obviously, I don't remember her exact title.
The switchover wasn't what crushed me. Helen Mirren is worth the switch. (By the way, this tells you about the program I switched over to.)
No, what crushed me was the fact that - only a few minutes ago, I looked up Peggy Wood (She's the one who played the Mother Abbess in that movie, remember?) and discovered that her voice was dubbed (DUBBED!) for that movie when she 'sang' "Climb Every Mountain"!
All these years - the movie came out in 1965 - I thought I was listening to Peggy singing that magnificent song, and I was going to try and find a YouTube link for it. Boohoo!
[According to one source I found, however, it was Peggy herself who requested the dubbing, declaring that she was "too old" (73) to handle the vocals. Margery McKay/MacKay - I've seen her name spelled both ways - did the dubbing, which was uncredited at the time.]
I went to YouTube anyway, and found the original soundtrack from the movie. I had the intention of posting it here for you (my link thingee is working again) but the video is rather dark, and so I listened to a few others and found one that I think you might enjoy.
It's in the same key as that of the film score, and the visuals are lovely. I do not know the vocalist's name. Here it is ...
If you'd like to read more about Peggy Wood's career, here's the best link I could find.
