Where is the recording of Donald Lambert's "Elegy"?

[cuberdrift]

So, apparently Donald Lambert played over a bunch of classical pieces. The most popular of these is his arrangement of "Anitra's Dance" by Grieg.

However, I've just discovered that there exists a sheet music transcription of his "Elegy". But I can't find the recording anywhere. Might anyone know here where such a recording exists?

Thanks!
