I got to thinking of this last week since my copy of "Back to the Egg" includes "Goodnight Tonight" (an ok single), "Daytime Nighttime Suffering" (a terrific B-side), and "Wonderful Christmastime" (your mileage may vary, but my sense is that it's generally loathed).

"I'll Give You A Ring", the "Take it Away" B-side, is a good song, too.
