2/24/94 - JT appeared as himself in an episode centering on Homer Simpson
being chosen by NASA for a space mission. JT was called in to calm the
frantic crew by singing a couple songs for them over the radio. He
started with "You've Got A Friend" and later sang part of "Fire And
Rain," at one point changing the lyrics to avoid saying "flying
machines in pieces on the ground" since the rocket was expected to
burn up on re-entry. Hilarious inside jokes were made in reference to
JT's home on Martha's Vineyard and his friendship with Art Garfunkel.
JT suggested a way to save the astronauts which resulted in
Homer being sucked out of the spaceship. JT's response when the NASA
head honchos turned on him angrily was "Gotta go." And he did.
Look for sampled recordings of JT's appearance on both the Web home
page and the FTP site.
