if you go to isohunt:
www.isohunt.com
put BLUE BIRD - Ikimono-Gakari in the search box, you'll get a whole bunch of links to pop up for download. it's the very first one you want to download that says [GENERAL]Ikimono-Gakari - Blue Bird [Naruto Shippuuden OP3]. it the whole song not the tv version.
to your question belldandy, it's brand new breeze. i think if you put in primo passo in the search box, you'll go down the links till you see nipponsei's upload of the cd single for it.
hopefully that helps.
