I think it is has been argued convincingly that the Andante and Finale
(op. 79) are in fact the other two movements of the E-flat concerto (op.
75), and that the composition was indeed complete - although Tchaikovsky
did not live to orchestrate the two remaining movements, and Taneyev, after
completing that task, decided to have them published separately.

Bogartyryev(sp?) also combined these three movements (plus a scherzo whose
origin I do not know) in his "reconstruction" of a Tchaikovsky Symphony No.
7 - the material for the concerto may indeed have come from a symphony that
Tchaikovsky was working on during his last years, but that he supposedly
discarded.  The three-movement concerto is much more enjoyable than
Bogartyryev's reconstruction, though.
