I've never heard Paul Siebel's "Louise" by him or Bonnie Raitt, but my friends (who have) use these chords:
A B7 E7
THEY ALL SAID LOUISE WAS NOT HALF BAD
D E7 A
IT WAS WRITTEN ON THE WALLS AND WINDOW SHADES
A B7 E7
AND HOW SHE'D ACT THE LITTLE GIRL
D E7 A
THE DECEIVER, DON'T BELIEVE HER, THAT'S HER TRADE
D E7 A
SOMETIMES A BOTTLE OF PERFUME
D E7 A
FLOWERS AND MAYBE SOME LACE
D E7 F#m
MEN BROUGHT LOUISE 10 CENT TRINKETS
D7 E7
THEIR INTENTIONS WERE EASILY TRACED
