Blue Bird

[caio.taiko]

The Blue Bird has been posted in the Lyrics section or somewhere else (I really can't remember, lousy memory XD), but I do remember about some parts of the lyric that nobody could understand clearly: the first words (... kumo ga nagaretara) and somewhere near the Chorus (kimi wa sotto ni mamotta ...).

This second part, I think is already solved (kimi wa sotto ni mamotta kono se no tsubasa).
But regarding the first one, I tried to listen to it several times and never could understand a word that could fit. Today, I was playing the BlueBird PV and I think i heard it correctly:
Kirei na kumo ga nagaretara [kirei na kumo = beautiful clouds]
!!!!
What do you guys think?
