Here's how Ellington's specialist Eddie Lambert describes this session in his wonderful book Duke Ellington: A Listener's Guide (Scarecrow Press, 1999): "This session was the first of two for the Gennett label, each of which produced two titles. With Miley absent again, the band was that of the preceeding session, augmented by trombonist Jimmy Harrison, and by Prince Robinson and George Thomas, both doubling clarinet and tenor sax. Thus say the discographers, but aurally the band sounds smaller, and it seems probable that Harrison and Thomas were used solely as vocalists. "'Wanna Go Back Again' Blues" (with a vocal by Thomas) includes the first instance on record of imaginative scoring by Ellington, albeit briefly and in a novelty mold. After the band introduction, Hardwick's playing of the theme on baritone is skillfuly offset by two clarinets and the trumpets. This is a considerable contrast to the conventional saxes-against-brass scoring in the eight-bar verse and in the bridge of Irvis's chorus. "If You Can't Hold The Man You Love" (vocal by Jimmy Harrison) has a passage for plunger-muted trumpets which is a distant precursor of what Ellington called his "pep section" in later years. The style, however, looks back to the King Oliver manner and is reminiscent of Oliver's two-cornet breaks with Louis Armstrong on the Creole Jazz Band recordings of three years earlier. Irvis has a terse eight bars but otherwise the performance is dull, despite an attempt to ginger up the last chorus by having Robinson play a piping clarinet improvisation against a written ensemble. This foreshadows a device used regularly and successfully in later years, but in this instance it fails to counteract the prevailing medriocrity".
It should be noted that Lasker's recent statement agrees with Luciano Massagli's and Giovanni M. Volonté's The New Desor (Milano, 1999) (thanks to David Palmquist and Ken Steiner for pointing this out to me) and with the current on-line edition of Tom Lord's discography.
