Thanks bsp & helio. I was going by what was in the programme book (in a pdf file on the website) which didn't mention (as far as I ould see) Cortese. It also doesn't say anything about it being sung in Chinese, so a little more investigation is needed before I book! Pity - I've heard Karen Cargill sing it with the BBCSSO & she was wonderful (it was issued as a BBCMM CD)
