Something I taught/demonstrated this past weekend at the NY Stick Seminar was that many songs are based simply on ii V. That would be Dm G(7) (in C). Not necessarily resolved to the One chord.
Holding Back The Years
Spooky
Stormy
I Wish
Son of Mr. Green Genes
Oyo Como VA
Evil Ways
Many standards are ii V I. Not necessarily referring to that

Any more?

"Chameleon" by Herbie Hancock
ii7 > V7
Bb min7 > Eb7

always wondered when you play the ii chord how do you know it's ii and not i ?
or even ii V
can't i just call it i IV ?

Indeed Chameleon! Good call Ted.
Boaz, that progression is both
ii V in a Major key
I IV in Dorian
It's the same thing just depends on where the resolution might be heard.
