I haven't heard much of Kenny G but I think that both he and Louis were popular artists. Kenny G may have done an overdub on Louis's "Wonderful World" but the latter was a pop song, not a jazz classic. Now if Kenny G had decided to re-record the West End Blues or Heebie Jeebies, that might be a different issue. But one pop performance on top of another doesn't seem much to get het up over.BTW, one of Louis's favorite bands was reputed to be Guy Lombardo. If Louis were to record an overdub with Lombardo's band, would anybody be upset?
Pat Metheny is decrying the lack of respect given to jazz today by the general public. That may be justified but Kenny G. is a popular artist. Pat Metheny would not like the popular music mixed with jazz apparently? Or is it that Pat Metheny would like some of those popular accolades?
When Louis was at the height of his jazz career, he wasn't yet a popular artist.
Maybe Pat Metheny could do an overdub on "Hello Dolly" and make a little splash in the pop market. :)
