Extant unpublished recordings:

Beethoven's 32 Sonatas were recorded twice, once with Cortot's comments. They ought to be in Pathe Marconi's Paris archive. They may date from 1957 and might be poorly played.

A film exists of Cortot playing most of Debussy's Children's Corner Suite. The tasteless scenario obscures Cortot throughout, except for a few rare moments allowing glimpses of him and his hands. What a lost opportunity!
