Even at 91, Pete Seeger is in full voice - and passion - singing for a Solartopia. He co-wrote the song with Solartopia author, Harvey Wasserman. Singer-songwriters, Dar Williams and David Bernz, accompany him on the video along with a small children's choir. The film was created by award-winning filmmaker, Dan Keller. The song also appears on a Pete's new CD, Tomorrow's Children At the end of the piece, Seeger, with his customary and unflagging optimism, proclaims these the most exciting times to be living in.
