The Pink Floyd pig from the cover of their 1977 album 'Animals' flew over London's Battersea Power Station once again yesterday (Sept. 26), marking the kick-off of the band's massive "Why Pink Floyd?" reissue campaign and hopefully not causing too many fender-benders from gawking drivers.

This was the second time Pink Floyd flew a pig over the station. However, this was not the original inflatiable from the 1976 photo session that resulted in the iconic 'Animals' artwork, but rather a newly created replica. The plan was to use the same blimp, but 35 years in storage apparently made that one pig that couldn't fly.

All fourteen studio albums from Pink Floyd's storied career have been re-issued in digitally remastered editions today (Sept. 27,) and are available on their own or as part of a massive box set. In addition, their 1973 landmark 'The Dark Side of the Moon' is available in 2-disc "Experience" and 6-disc "Immersion" box set form.

Floyd drummer Nick Mason kicked off a week-long tribute to his former band on 'Late Night With Jimmy Fallon' last night, talking with the show's host about the deluxe packaging for the box set and enjoying a tribute performance of 'Breathe' from new generation rock band the Shins.
