Walking bass help on Black Coffee, please!

[Bass Momma]

I'm having trouble handling the |C7#9 Db7#9| bars on Black Coffee. I understand that the Db7#9 in a subV, a tritone sub for the V of C7...

The A progression goes:
| C7#9 Db7#9 |C7#9 Db7#9 | C7#9 Db7#9 | C7#9 Gb13 |
| F9. | F9. | C7#9 Db7#9 | C7#9 A7#9 |
| D-7 | D-7/G | C7#9 A7b9 | D-7 G7#9 |

I think I'm hearing a couple of versions do something like a R 5 on the C7, then R b5 on the Db7, keeping that "riff" on each of those bars through the song. That does seem to work.
Any other ideas/insights?

I searched around and found over a dozen songs called "Black Coffee". Can you narrow it down for us?

Ah, yes - sorry! Got caught myself when I landed on a heavy metal version this morning.
I'm thinking of the Sarah Vaughan or Peggy Lee one. SV is in C#, we’re playing our singer’s key of choice….

It's all in there in that Sarah's version.

Keep it simple. The Db7 has a #4 in it, so going 1-5-b5 is good because you have a perfect fifth interval to go back to C (G-C) on that Db7. Sometimes as bassists we forget our primary role of playing the root while the others are playing chords...

When the chord changes every two beats, there’s not enough beats to do any real walking. All you have time for is root-leading tone, root-leading tone.

When the chord changes every two beats, there’s not enough beats to do any real walking. All you have time for is root-leading tone, root-leading tone.

When you have 2 chords per bar, you sure can walk a smooth line, in particular by using other chords tones than the root (the point is to select chord tones that provide a smooth transition from one chord to the next).
For the case you ask about (| C7#9 Db7#9 |C7#9 Db7#9 | C7#9 Db7#9 | C7#9 Gb13 | F9 etc... ), you could walk the first 4 bars like this:
| C(R) Bb(b7) Ab(5) B(b7) | C(R) E(3) F(3) Ab(5) | G(5) C(R) Db(R) F(3) | E(3) G(5) Gb(R) E(b7) | F(R) etc...
