Great episode and totally didn't feel overblown with having (effectively) four shows this week. The others were bite size.
Anyway, I loved the discussion about the Beatles and thought I'd just throw my two cents in there about the mono vs. stereo aspect of the Beatles catalog. Chris mentioned how Sgt. Pepper's was a simple stereo mix (vocals on right, guitar on left, etc.), but the Beatles themselves had nothing to do with the stereo mixing, only the mono mixing. Many fans will argue that the true mixes are the mono mixes, which is a big reason the recently released box set in mono costs more than the stereo box set . . . it's more for collectors and they'll pay whatever Apple asks of them.
Moving on.
