Here's the original in the Preface to "Milton"

The music to Jerusalem which we get at the Last Night of the Proms is Parry all right, but in Elgar's arrangement. What a shame we no longer have John Barbirolli to conduct and Kathleen Ferrier to help with the singing.

Paul Robeson recorded a cracking version - I suspect at Abbey Road. Managed to get it played at my mum's funeral.
