I chose "I'll sing the song of your life" as title because since Eco is an errant bard, his goal is singing a wonderful song, and knowing Belca he decides that that song will be the one of his life! He look at Belca as a hero and he's determinated to do of his life, his best song.

Eco is a funny character and many canonic titles could be good for him, but I prefered choosing something perfect for the dedication of his life.
