In reference to Brian Cather's question about Max Kortlander on Pathe
or other recordings, I can provide some information.

The Kortlander 78-rpm recording of Euday Bowman's "12th Street Rag"
which Brian refers to (Pathe 20467) is actually a lateral cut record.
The vertical cut record was pressed in England and issued as Pathe
Feres #1390.  Both issues are the same takes, and each side features
Max Kortlander and Victor Arden (pseudonym of Lewis J. Fuiks) in a
piano duet.  The flip-side of the record is Max Kortlander's 1920 pop
song entitled "Anytime, Anyday, Anywhere."

Max Kortlander's piano roll of "12th Street Rag" was issued on QRS
1188, a word-roll.  It is a solo performance, not a duet, and bears
no direct similarity to the duet recording on Pathe.

Interestingly though, the QRS roll of "Anytime, Anyday, Anywhere"
(#987) was issued as a duet played by Max Kortlander and Lee S.
Roberts.  This roll is much in the same style of the 78-rpm record,
although it is by no means an identical performance.  Both Pathe
sides are acoustic recordings of hand-playing, and piano rolls were
not involved in the recording session in any way.

As far as other appearances of Max Kortlander on 78-rpm records go,
there are only two others of which I am aware.  One is a duet chorus
with Victor Arden in the middle of a dance band recording on Brunswick.
My 78's are buried now, so I cannot confirm the title or band! The
other is an accompaniment to vocalist Jane Green on the Harmony label,
and the tune is "Looking At The World Through Rose Colored Glasses."

Max was not given credit on this record, but my information that he
was accompanist comes from the Kortlander family via his brother,
Herman Kortlander.  I don't believe there were any other commercially
released recordings on disc.  In circa 1951 some private acetates were
recorded by Max and J. Russel Robinson during a get-together at QRS,
but these were never issued.

All Best,
