Well i can be hard-hearted, but my heart melts for a ballad--

there is one an old (14th century) french one (bel please help if you know the french) the Chant d'amour i think
"the songs of love, they fill my heart with joy
the songs of love will last my whole life long.."

the traditional tune was modified slightly, and used by the King, (Elvis) for "Fools rush in, where wise men fear to go"
