Bob pointed out this obscure fact while signing off today on his XM Radio show, Theme Time Radio, the second straight week he has done birds as his theme. It followed Prince's When Doves Cry, and came just before his final quote, from William Blake. "No bird soars too high if he soars with his own wings."
