Les, thanks as always for the links to your article database. I enjoyed the one about the 1987 Peltier benefit as I didn't know much about it, and I learned a lot. I wonder what other songs she did besides "Lakota" & "Tax Free"?
"Joni Mitchell, supported by a jazz-accented band including saxophonist Wayne Shorter and bassist Larry Klein, followed with a 40-minute set that reinforced her reputation as a daring, independent-minded songwriter and singer. Rather than lean toward her most melodic and best-known early work, she concentrated on recent material, previewing a song ("Lakota") from her upcoming album and offering a dramatic rendition of "Tax Free." The latter tune, from her 1985 "Dog Eat Dog" LP, rips at rightist televangelism with uncompromising ridicule and fury." Bob NP: Fats Domino, "I Want To Walk You Home"
