                                     PART I

Item 1.  Business.

         Mills Music Trust (the "Trust") was created by a Declaration of Trust
dated December 3, 1964, for the purpose of acquiring from Mills Music, Inc.
("OLD Mills") the rights to receive payment of a deferred contingent purchase
price obligation payable to OLD Mills. The purchase price obligation arose as
the result of the sale by OLD Mills of its musical copyright catalogue to a
newly formed company ("New Mills").

         In payment for the aforementioned catalogue, New Mills agreed to make
quarterly payments to Old Mills (the "Contingent Portion") measured by the
royalty income generated from the catalogue and, subject to certain limitations
and conditions, from any copyrights thereafter acquired by New Mills.

         The contingent Portion for each quarterly period to and including the
last quarter of 2009 is to be an amount equal to the excess, if any, of (a) the
gross royalty income from the exploitation of the purchased copyrights during
such period (whether received by New Mills, its affiliated companies or any
other party) over (b) the sum of (i) the greater of (x) 25% of such gross
royalty income or (y) the lesser of $87,500 (as adjusted for inflation by
reflecting changes in average weekly earnings of employees in the printing,
publishing and allied industries since 1964) or 30% of such gross royalty
income; and (ii) royalties required to be paid to composers, authors and others
with respect to the existing copyrights. If the Contingent Portion as so
computed is less than $167,500, then the Contingent Portion will be computed on
the basis of the gross royalty income and related expense of New Mills, its
affiliated companies and their successors and assigns during such period not
only from the exploitation of purchased copyrights, but also from any copyrights
originated or acquired by New Mills and its affiliated companies subsequent to
December 5, 1964 (with the deductions referred to in (i) and (ii) above) except
that, when computed in this manner, the Contingent Portion cannot exceed
$167,500. In addition, for any quarterly period in which the contingent portion
as calculated above exceeds $250,000, the percentage specified in (x) above is
increased to as high as 35% based upon gross royalties for the quarter.

         Commencing with the first quarter of the year 2010, the Contingent
Portion for each quarterly period is to be an amount equal to 75% of the gross
royalty income of New Mills and/or its affiliated companies and their successors
and assigns from the exploitation of the existing copyrights for such period,
less the related royalty expense.

         The acquisition purchase agreement provides that the obligation to make
payments will terminate on the last day of the year in which the last purchased
copyright, or a renewal thereof, expires and cannot be renewed. When the
existing copyrights begin to expire, the size of each payment through the year
2009 will become increasingly dependent on the success which New Mills has in
acquiring and exploiting new copyrights.

         The composition of Old Mills Catalogue is estimated to be in the excess
of 25,000 titles of which approximately 1,500 are at present producing royalty
income. The major portion of the royalty income generated by the catalogue in
recent years, however, was produced by a relatively small number of well-known
songs, many of which have remained popular and have generated substantial
royalty income over a long period.

         The Declaration of Trust prohibits the Trust from engaging in any
business; the Trust's sole activity is the receipt of the periodic installments
of the purchase price and the distribution thereof, (after payment of expenses
of the Trust) to the owners of units of beneficial interest in the Trust.

ITEM 2. Properties.

         The administrative office of the Mills Music Trust is at 140 Broadway,
New York, New York 10015. There is no expense being charged or paid for office
space and office equipment being utilized by the Trust.

ITEM 7.  Management's Discussion and Analysis of the Trust's
         Receipts.

         The Trust's receipts are derived principally from copyrights
established prior to 1964 and such receipts fluctuate based upon public interest
in the "nostalgia" appeal of older copyrighted songs.

ITEM 8.  Financial Statements.

         The financial statements begin on page 5 of this report.

                                MILLS MUSIC TRUST
             NOTES TO STATEMENTS OF CASH RECEIPTS AND DISBURSEMENTS
                       THREE YEARS ENDED DECEMBER 31, 1999

Note 1.           Accounting Policies and General Information.

         Mills Music Trust (the "Trust") was created in 1964 for the purpose of
acquiring the rights to receive payment of a deferred contingent purchase price
contract obligation payable by Mills Music, Inc. ("Mills"). The contingent
payments are determined quarterly and are based on a formula which takes into
account gross royalty income paid to composers, authors and others, and less
amounts deducted by Mills in accordance with contract terms.

         Payments from Mills to the Trust are made in March, June, September and
December and include net royalty income of the preceding calendar quarter. The
payments received are accounted for on a cash basis, as are expenses. The
Declaration of Trust requires the distribution of all funds received by the
Trust to the unit holders after payment of expenses.

         The statements of cash receipts and disbursements reflect only cash
transactions and do not present transactions that would be included in financial
statements presented on the accrual basis of accounting, as contemplated by
generally accepted accounting principles.

Note 2.  Federal Income Taxes

         No provision for income taxes has been made since the liability
therefore is that of the unit holders and not the Trust.

Note 3.  Related Party Transactions

         The Declaration of Trust provides that each trustee shall receive
annual compensation of $2,500 per year for services as trustee, provided that
such aggregate compensation to the trustees as a group may not exceed 3% of the
monies received by the Trust in any year, and reimbursement for expenses
reasonably incurred in the performance of their duties. The Declaration of Trust
further provides for reimbursement to the corporate trustee for its clerical and
administrative services to the Trust. Accordingly, HSBC Bank USA (formerly
Marine Midland Bank), the corporate trustee, also receives reimbursement for
such services (including services performed as Registrar and Transfer Agent of
the Certificates representing Units).

         The Declaration of Trust also provides, that if in the future any
trustee performs unusual or extraordinary services, reasonable compensation for
such services shall be paid, subject to certain limitations and to prior
confirmation by a majority in interest of Trust Certificate holders.

Note 3.  Related Party Transactions (continued).

         Pursuant to these provisions, disbursements were made as follows for
the years ended December 31:

Marine Midland Bank) as
registrar and transfer agent              5,542      5,839       5,932

Note 4.  Royalties

         (a) The original (1964) sale agreement assumed by the Trust's
collecting/paying entity ("EMI") provides for a revised royalty calculation when
the remittance to the Trust is less than $167,500 for the quarter. This occurred
in the quarter ended December 31, 1999, for which the remittance was $155,717.
EMI did not calculate that quarter's payment using the revised royalty
calculation, and has been notified about this matter. Additional monies due to
the Trust, if any, under the revised calculation would be capped at an amount
that, when added to the prior distribution, would not exceed $167,500. The
timing of the receipt of any additional monies due to the Trust is dependent
upon EMI's ability to provide the information required under the revised royalty
calculation.

         (b) In addition, EMI made a computational error in its remittance for
the fourth quarter of 1999, resulting in a $19,000 overpayment.

         The net effect of (a) and (b) above will reduce the Trust's revenue in
a future quarter. The maximum revenue effect to the Trust ($19,000), if no
additional funds are due from EMI, is $.07 per unit.

Note 5.  Royalty Examination

         The Trust's claim against Belwin Mills Publishing Corporation, the
former administrators of the Old Mills Catalogue, in connection with a 1987
royalty examination is pending final resolution by the Trust. It cannot be
determined at this time, what, if any, amount may ultimately be received by the
Trust. No examination of royalty information has been performed subsequent to
1987. However, the Trust has arranged for a limited royalty examination to be
performed in early 2000.

The Trustees and Unit Owners
Mills Music Trust


We have audited the accompanying statement of cash receipts and disbursements of
Mills Music Trust for each of the years in the two years ended December 31,
1999. This financial statement is the responsibility of the Trust's Management.
Our responsibility is to express an opinion on this financial statement based
on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

As described in Note 1, this financial statement was prepared on the basis of
cash receipts and disbursements, which is a comprehensive basis of accounting
other than generally accepted accounting principles.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the cash receipts and disbursements of Mills Music Trust
for each of the years in the two year period ended December 31, 1999, on the
basis of accounting described on Note 1.
