Ladybird and Just Friends are both perfect examples.Cool, thanks Heavy, I'm starting to get it now. Maybe in retirement I'll have time to take up jazz theory. It's fascinating stuff.
I'd also say "The Days of Wine of Rose", bar 7 and 8. Depending on the version you listen to or the leadsheet you consult you may see it written as Db7 (so no Bbm7). It also doesn't resolve to I but iiim instead, however these are very similar sounds - try playing Ebmajor7 and then Gm7 on the piano. Or play a Ebmajor 9 arpeggios (Eb G Bb D F), then a Gm7 arpeggios (G Bb D F)....
I tend to think of "four minor" as sound or harmonic place which a tune can "visit". The majority of standards feature it, sometimes as ivm sometimes as bVII7, sometimes as iiihalfdim (e.g. I Love You). Lots of pop tunes do it too
