PLEASE HELP!

HAVE BEEN SEARCHING FOR ALMOST 5 YEARS FOR:

CAROLINE IN THE CITY (EPISODE #408, 11/1998)

NAME OF SINGER/SONG OF FEMALE SOPRANO OPERA SINGER

* CAROLINE WENT TO SEE AN OPERATIC RECITAL OF A TEMPERAMENTAL FAMOUS FEMALE OPERA SINGER AND IN THE PROCESS ANNOYED HER.

THE MUSIC THAT WAS PLAYED DURING THAT SEQUENCE WAS BEAUTIFUL.

PLEASE, IF ANYONE HAS ANY INFORMATION REGARDING THIS EPISODE/SINGER/SONG, I WOULD GREATLY APPRECIATE IT.

I KNOW THE ACTRESS WHO PLAYED THE SINGER WAS NATALIA NOGULICH AND THE CHARACTER WAS NAMED KAY REYNALDO BUT I DONT KNOW WHO THE "REAL SINGER/SONG" WAS DONE BY.

THANKS ALOT!
