Nice...thanks!
As you probably know, the song was about Jeff Porcaro’s girlfriend, Rosanna Arquette.
As an aside, Jeff Porcaro first played on a Steely Dan album - Preztel Logic - as a secondary drummer. His mentor, Jim Gordan played on all but one track.
IIRC, Jeff Porcaro so impressed Becker/Fagen that he played all the tracks on their next album, “Katy Lied”
