In 1992 Glen Gould recorded (recording released by Sony) Liszt's transcription of Beethoven's 5th symphony. Roughly a year later (1993) he recorded the 6th symphony as well. Both of these recordings are known to me.
Recently I found the following youtube video which contains a recording of the second chapter of Beethoven's 7th symphony (Transcribed by Liszt of course). It sounds to me like it must be Glen Gould yet I haven't found reliable references anywhere in the internet vouching for the existence of such a recording. I desparately want to listen to the full recording (assuming there is one) but have no idea where to find it.
Question: Did Glen Gould record Liszt's full transcription to Beethoven's 7th symphony? If so, would it be possible to obtain a copy (even if only digital) of this recording?
