I am familiar with the word "happy", and I believe one of the 7 dwarfs was named "Happy". What is this "Happy" of which you speak? Is it a song? Why would I be familiar with it if, as I already said, I only listen to Sinatra or classical music? I'm at my desk at work listening to the Darmstadt Overtures by Georg Phillip Telemann as I write this.
The Rolling Stones had a song called Happy on their Exile on Main St. album back in the early 70s.
I clicked on the Weird Al clip and it didn’t sound like that.
And I didn’t recognize the Weird Al music for Tacky even as anything I’ve heard in the background.
