I found the reference to the Vincent Lopez rolls in the Nelson Barden
audio-taped interviews, transcribed and compiled by Dick Howe in the
book, "The Ampico Reproducing Piano", published by MBSI circa 1987.

On page 11 Barden asks Ampico artist and arranger Adam Carroll if he
recognizes the name "Domenic Savino".  (Howe spells the name "Domonic 
Sevino".)  Carroll replies, "Yes.  Arranged for Lopez.  Fine musician."

On page 218 Barden asks editor Angelo Valerio if he recognizes the name
Souvaine. (Henry Souvaine made a few classical Ampico rolls circa 1920,
and later was producer of the Metropolitan Opera radio broadcasts.)
Valerio responds, "Yes, Souvaine.  I had him, I remember."

Then Barden, apparently confused, remarks, "He was Lopez's arranger,
I believe; orchestra & band arranger, and Adam [Carroll] says that he
would make arrangements that they -- that Adam would then cut."

Since Henry Souvaine is known only in association with classical music,
the arranger for Lopez would more likely be Savino.  Is this name
listed in the orchestra's credits in the Brian Rust discography?

Elaine Obenchain, author of "The Complete Catalog of Ampico
Reproducing Piano Rolls," writes about Vincent Lopez:

 "Because of the large number of rolls that were assisted by another
  artist, these recordings are listed separately [as "Vincent Lopez
  asst."].  There has been some speculation that Lopez did not
  actually record all the rolls listed under his name.  While this may
  be true, it seems likely that at least some of them were done by him.
  Certainly it was necessary to have assistance on many of these rolls
  to create the effect of his entire band playing."

Ms. Obenchain doesn't present any evidence to uphold her theory.
Quite to the contrary, when Barden asks Adam Carroll if Lopez could
play well, Carroll replies (on page 10 of the 'Interviews'):

 "I knew him [Lopez] quite well.  He was not a pianist -- he was an
  arpeggio man.  In other words, he had a trick: he played with his
  right hand; left hand nothing.  He'd have the orchestra play softly.

 "Once he came to do a recording.  You know what happened: he brought
  the band with him (laughter).  Actually, he couldn't record the
  rolls; I made his rolls, Fairchild made his rolls. ... "

In the artist section of Obenchain is a short biography of Ampico
recording artist Domenico Savino:

 " ... At various times he conducted the CBS Symphony, orchestrated
  for Paul Whiteman and Vincent Lopez, and was chief editor of a
  music publishing firm. ... Many of his popular pieces were published
  under the pseudonym D. Onivas, which simply reversed his last name."

I believe that most of the Vincent Lopez Ampico rolls are the product of
two or three talents:  Domenico Savino, who created the marvelous orches-
tra arrangements, and Adam Carroll and/or Edgar Fairchild, who adapted
Savino's arrangements for the performance on the Ampico music rolls.
Vincent Lopez simply lent his name to the label.
