I am actually looking for the name of this part of Mozart's opera "Cosi fan tutte" performed by Rondo Veneziano. Video clip can be seen on this link:

Thanks in advance

A very wonderful piece, my wife is a classic music buff, and she knew the name of the opera the minute I played it, but she did not know the name of the individual piece

I have got the right answer on some other forum. It is aria Voi che sapete (The Marriage Of Figaro). I was misled by Rondo Veneziano's incorrect naming of this piece (Cosi fan tutte) so I went in the wrong direction, looking for the name of this tune.
