“Who’s That Lady?” – Donald Fagen, Michael McDonald, Boz Scaggs: The Dukes of September Live 2014
When The Dukes of September took the stage in 2014 to perform “Who’s That Lady?”, they weren’t just covering a classic—they were reviving a masterpiece with the full force of their musical maturity. Comprised of Donald Fagen, Michael McDonald, and Boz Scaggs, the Dukes were a supergroup stitched together from some of the most respected and sophisticated architects of American pop, soul, rock, and R&B. Their rendition of the Isley Brothers’ 1973 hit wasn’t an imitation; it was a celebration, delivered with reverence, technical brilliance, and the unmistakable cool that came naturally to all three men.
A Supergroup with Deep Musical Roots
The Dukes of September grew out of the earlier New York Rock and Soul Revue, a rotating collective that reveled in classic American music. By 2014, with decades of solo careers and band legacies behind them, Fagen, McDonald, and Scaggs brought unmatched skill to the stage. Each artist had carved a distinct identity:
-
Donald Fagen, the cerebral co-founder of Steely Dan, known for his jazz-infused chord progressions and sly storytelling.
-
Michael McDonald, the soulful voice of the Doobie Brothers and a master of blue-eyed soul.
-
Boz Scaggs, the smooth blues-rocker whose album Silk Degrees remains a masterpiece of 1970s craftsmanship.
Together, they formed a trio that could interpret the classics with authenticity while still leaving their personal fingerprints on every note.
A Song That Demands Skill — and the Dukes Delivered
“Who’s That Lady?” is no simple tune. The Isley Brothers’ version is famous for its shimmering guitar lines, sensual falsetto, and rhythmic finesse. Performing it live requires precision, restraint, and fire.
The Dukes of September delivered all three.
The 2014 performance opened with a tight, hypnotic groove from the band—a rhythm section capable of slipping effortlessly between funk, jazz, and R&B. The guitars glistened with the same psychedelic sheen that made the original so iconic. Then came the voices: blended, textured, and soulful in a way only three legends could achieve.
Donald Fagen: The Cool Narrator
Fagen didn’t take the lead on “Who’s That Lady?”—instead, he slipped into the role of musical architect. From behind his keyboard, he guided the arrangement with subtlety, adding those unmistakable Steely Dan flavors: sly accents, jazzy syncopations, and rhythmic sharpness. His presence kept the performance grounded, cool, and sophisticated. Even without singing lead, his fingerprints were everywhere.
Michael McDonald: The Soul Engine
McDonald’s voice was made for a song like this. His rich, smoky tone wrapped around the melody, giving it a depth and warmth that paid homage to the Isleys while adding new emotional dimensions. When he leaned into the higher register, the crowd erupted—proof that even decades into his career, his voice remained one of the most powerful in American music.
His backing vocal arrangements also elevated the performance, transforming the chorus into something lush and expansive. McDonald didn’t just sing the song—he infused it with life.
Boz Scaggs: The Smooth Craftsman
If McDonald was the engine, Boz Scaggs was the sleek finish. His vocals were silky, relaxed, and perfectly suited to the song’s sensual mood. Scaggs had an uncanny ability to convey emotion without oversinging—a skill honed over years of blues, rock, and soul performances. His phrasing added elegance, while his guitar contributions blended seamlessly with the band’s layered arrangements.
The Band: A Masterclass in Musicianship
The Dukes’ backing musicians were not merely a support ensemble—they were elite players, many of them long-time collaborators with Fagen, McDonald, or Scaggs. Their technical prowess allowed the trio to lean into improvisation and nuance.
-
The horn section added punch and sparkle.
-
The guitarists recreated the Isley Brothers’ signature tone with stunning accuracy.
-
The rhythm section laid down a groove so tight that it felt magnetic.
-
The backing vocalists wove harmonies that softened the edges and enriched the performance.
The result was a version of “Who’s That Lady?” that felt both familiar and freshly reimagined.
A Performance Built on Joy
What made the 2014 live performance unforgettable was the joy radiating from the stage. These were not young musicians trying to prove themselves—they were seasoned artists simply celebrating great music. There was laughter between lines, knowing glances, and spontaneous bursts of energy that only come from musicians who truly love what they do.
As the final notes faded, the audience rose in applause—not just for the song, but for the feeling it created. It was a reminder that great music never dies; it transforms, adapts, and finds new voices to carry it forward.
A Tribute That Became Its Own Classic
The Dukes of September didn’t cover “Who’s That Lady?” to replicate it. They performed it to honor the Isley Brothers, to celebrate the golden age of soul, and to bring that timeless sound into a new century. In doing so, they created a moment that stands proudly on its own—a live rendition that fans still revisit for its style, energy, and musical mastery.
In 2014, three legends asked a simple question:
“Who’s That Lady?”
The answer was clear—
She was the muse, the melody, and the spark that lit up the stage.
