loved reading your posts Matt Lucas!!
Lindsey actually mentioned Daniel Lanois when he was talking about bringing the outside producer for the Mac last time around, so he at least was on his radar.
bringing back Dashut and Caillat harkens to Rumours II suggestions. it's been done, let's move forward people, see what some others can do.
my personal preference - give Froom a chance to finish what he started. but i can see Rick Rubin arguments too, and there were others on these boards who brought up his name in the past. (possibly even Lindsey mentioned Rubin at the same time as Lanois? can't remember exactly, but he did list 2 or 3 possible producers.)
