Perhaps a couple more guitar duels would have eased some of the tension & there would have been less of a shift to long Henley ballads.
Regarding Glenn's very harsh words on why he felt they couldn't use Felder's contibutions, I suspect that he thought that Felder only wanted to push Felder & had no interest in how the rest of the band were supposed to sound, hence the 'where do you sing' comment.
