"For my money,the old time waltz, that literally sends chills up my spine is the beautiful "Parlez-Moi D'amour" (Speak To Me Of Love).
I could be wrong,but I think its French-Canadian in origin and the best version I ever heard was recorded by Catherine McKinnon in her Singalong Jubilee days, on an album called "Voice of an Angle"

i presume he meant Voice of an Angel....

I just realized that the old camp tune that we used to sing in
Girl Scouts, RISE UP O FLAME is in waltz tempo.
Rise up, oh flame, by thy light glowing.
Show to us beauty, vision, and joy. ...

i think it is sung as a round.
