"Why Is the Sky Blue?" - Nick Cope

Artist: Nick Cope 

Song: "Why Is the Sky Blue?" 

Album: Why Is the Sky Blue? 

Description: The English musician Nick Cope and his son Burt have made quite a few videos together.  Their new one, for the title track to Nick's third album for families, is from the perspective a kid who asks a lot of (accentuated, well-rhymed) questions, and so the Copes' lo-fi animation style fits perfectly.
