The other version has the right progression, just in the wrong key. The song
actually starts a tone up on A instead of G. The progression is A, E, D, E. Here are the lyrics.
Little ditty, 'bout Homer and Marge, Her heart was as big as his stomach was
large
Oh yeah, they say love goes on long after the grilled cheese sandwich is gone
The rest of the song plays during the credits at a slower tempo
That's the story bout Homer and Marge, Two folks I helped out for a nominal
charge
After Homer went gay, they patched up their schism But the dude never dealt
with his alcoholism
Weird Al saying: Oh Yeah, the credits go on, long after the viewer's
interest is gone
Weird Al had fun on this show even if it was just a brief cameo
