O, liebe

O lieb, so lang du lieben kannst, S.298 - Brahms / Liszt: Lieder - Liszt, Franz [Composer]

, you recognize it from somewhere?
Of course.
The piano version of this song "Liebestraume -Nocturne No.3" is one of the most famous classical melody of all time. Even if you don't know anything about classical music, you know this tune.

Funny thing is that, even among the classical musicians and afficionado, the original version is virtually unknown.

As the composer puts it, the song is "frivolous"... *laughs... but it is simple and passionate. The lieder(song) is rarely performed, but I think this recordings delivered the core of the composer's intentions.
