"There is one thing I neglected to tell you: I am going to use your music to make you Earthlings a little more flexible in your dealings with my distant planet. And you, my musical friends, will make it possible. Roll the tape!"

"Now let's show them what our Spectra sound can really do!"

"Ahahahahaha! Their robot planes were no match for our music!"
