I have a videotape of a concert done in Vancouver BC at the aquarium there. The orchestra played Alan Hovanes' "And God Created The Great Whales",while the captive killer whales went through routines to the music.

The scenes of the rehersals were particularly fascinating,as recordings of Humpback songs were played to go with the music.These killer whales had been captve their entire life and had never heard the songs of the humpbacks.Their first reaction was a complete cessation of activity and what appeared to be attentive listening.They then burst into frantic activity, splashing the orchestra members, and paying no attention to the signals of their trainers.

They eventually settled down and the show went on.
