Alain Fantapié reported in Diapason magazine, No. 195, March 1975: "An interpretation of BWV 146, conducted by F. Prohaska, has disappeared from American catalogue, which exists only coupled on Riverside album with Cantatas BWV 69 and 120 performed by the Louisville Bach Society and American singers. This record has never been available in France."
