I've checked and believe to have found the identity of the unknown
A-roll which Mark Forer described in 990524 MMDigest.   The roll is
Clark #466, "Radio's Bright Flashes."  The line-up follows:

 Clark No. 466   "Radio's Bright Flashes"

 1.  After The Storm
 2.  Don't Mind The Rain
 3.  Land Of My Sunset Dreams (waltz)
 4.  Why Did I Kiss That Girl?
 5.  There's Yes! Yes! In Your Eyes
 6.  You Can Take Me Away From Dixie
 7.  Toodle-Oo
 8.  Adoration Waltz
 9.  I'm All Broken Up Over You
10.  Never Again

Tune #1 could possibly be the QRS arrangement by Charley Straight,
#2 the Arden & Kortlander, #4 the Kortlander arr., #6 Sid Laney (Cook),
#7 Herbert Clair.  These I remember offhand, the others can easily be
checked via reference to the Billings rollography.

With a roll of this comparatively early vintage for Clark, it's a
mistake to assume the use of QRS masters without auditioning the roll.
The Clark staff turned out a great deal of superb arrangements and
certainly by the approximate date of this roll (circa 1923-4) the odds
are just as good of finding a Clark master as a QRS.   The difference
is always like night and day in the comparisons I've come across.

All Best,
