What song is the name of this Hayley Westenra song?

It's called Wiegenlied, and although it's sometimes attributed to Mozart ('Schlafe, mein Prinzchen' - 'Sleep, my little prince'), it is actually composed by J. Bernard Flies, an amateur composer born about 1770. Sadly, this song can only be obtained by buying the Japanese version of Hayley's album "Odyssey".
