As a result of this recording the following letter was sent to the Dean of St John's (the Revd S. W. Sykes) by Robert Armstrong (Secretary to the Prime Minister):
10 Downing Street
12 October 1972
Dear Mr Dean,
The Prime Minister [Sir Edward Heath] has asked me to thank you for your letter of 11 October. The recordings of Haydn Masses which he gave to the Pope were the six recordings published by Argo; and of course, as you know, the Saint John's College Choir are included in five of the six. The Prime Minister is glad to think that it may please the Choir to know that the sounds of their voices may well be echoing round the Vatican.
