Just The Two Of Us - Grover Washington Jr & Bill Withers
The chord progression D♭maj7 – C7♭9 – Fm7 – E♭m7 A♭7 of its intro and verse can be thought of as a double-time modified reordering of the first four bars of the "Sunny" chord progression.
"Just the Two of Us" restarts this progression but settles on the minor tonic: D♭maj7 – C7♭9 – Fm7 – %. Its chorus inserts an additional Em7 chord to chromatically descend from the first Fm7 to E♭m7 chord
