Just gave 1/19 a listen. Excellent, and thanks for suggesting it. Totally agree about Imagine vs. Elinor Rigby. Also love the Expressway but may like the After Midnights a tad better because I think it has a little more variety, particularly as done in early 80 where the return after Rigby is fast with a big climax while the one before Rigby is a little more laid back. (just listened to a couple of these again also)
If you like 1/19 and have not heard 12/20/70, I recommend giving it a listen. The Expressway > Jam > Georgia on my Mind is something I like even better than the 1/19.
