I wonder what’s going on this these animals heads as they’re hearing this. Interesting.
I wouldn’t doubt if this elephant genuinely enjoys the interaction, and MIGHT even appreciate the music as a unique and unusual auditory stimulus?
Horse: “Wait… is that my hairs?? Why is my hair making funny noises?? This smells odd.”
The cows were so cute. Actually, all the animals were. It’s interesting watching their reactions. The innocence in these animals is a beautiful thing.
Isn’t it obvious what the cows are thinking?
“Needs more cowbell!”
You’re welcome.
And don’t forget the jammin’ golden retriever…
Video 1 - “Cowabunga man!”
Video 2 - “I’ll never forget that melody, as long as I live.”
Video 3 - “That’s a cello of a different color. Is that Beethoofen you’re playing?”
The cow enjoyed this and will remember it for heifer and heifer. ker tunk
The cow and horse may have been thinking “Let’s Go Branding!” 
I believe the elephant said “Make India Great Again!” It’s no surprise there’s no donkey in the list, it’s poll numbers have sunk too low to matter any more. 
Do cows call it cowbell?
The cows say “It’s the strangest thing we’ve ever herd.”
