Still looking if you happen to come across this.
There was a complete “Hayy Together” soundtrack issued when the film came out. It not only includes that version of the song, but the other significant music used in the film, chiefly by Frank Zappa and Astor Piazzola.
I saw two available to import on Amazon, but they are $100-$200. I downloaded Tango Apasionado and would love the rest, but the cover version is the only one I can’t find for individual purchase.

Does anyone know where I can find the cover version of the Turtles “Happy Together” that played over the credits? I’ve seen it credited to a Daniel/Danny Chung.
