John Camp (RGS 1954-60) sent me these two "official" photos, taken by the photographers Cyril Roberts, of the performance
"The romantic lead, Ralph, was very well played by J. E. Camp, who combined the great virtue of audibility with a pleasing and powerful tenor voice. We look forward to his future performances. His leading lady, J. F. I. Pryce, " sold" his feminine charms as Josephine quite convincingly and sang his rather difficult solos well"
