I think the remarks about Waronker's contribution to Lightfoot's success are completely justified. That topic has been discussed here before, and perhaps "enhanced" would have been a better choice of words than "sophisticated", but Waronker definitely focused on the music first and not commercial success. In fact, when Lightfoot received his (dang....what was the one where Dylan introduced him ?) award, Waronker was included on his list of 'thank-yous'.
