I know a dog named Catherine who sings, with Dawn Upshaw, Barber's
"Knoxville - Summer of 1916" - much of the time in harmony. (maybe my
imagination). During the introduction she gets more and more agitated
and starts to sing, but when Ms. Upshaw comes in she goes crazy.
I knew another dog who sang in thirds with her mistress - quite amazing.
I have a feeling it was the other way around, but somehow the tunes made
some kind of sense.
