Reelin In The Years

On Saturdays I am working through "The Best of Steely Dan: An Inside Look at the Guitar Styles of Steely Dan". The tab seems accurate, the CD is useful, and the text is reasonably insightful. At the core "Reelin In The Years" is a straightforward G-D-A song, but there is a bunch of harmonic stuff happening in the solos that is hard to nail. Learned this one pretty much by rote repetition, hopefully I will gain some understanding from future efforts. I'm in the right channel, the original is in the left channel.
