I don't know why (I love you) rolling stones lesson

This song was written /recorded by Stevie Wonder in 1968 but covered by the Stones during the Let it Bleed sessions in July 1969 . The Stones version is definitely quite a bit different sounding (with tremolo) ,although its in the same key and has the same chord structure . In the intro here I'm playing along w/Keith's open G part I recorded earlier
