I meant to post this earlier: In what has to be the strangest death coincidence since John Adams and Thomas Jefferson both died on the 50th anniversary of the signing of the Declaration of Independence, original Jefferson Airplane member Signe Anderson died the same day as original Jefferson Airplane member Paul Kantner, both aged 74! Signe Anderson was from Portland and was replaced by Grace Slick. Here’s the story from Rolling Stone: http://www.rollingstone.com/music/news/signe-anderson-original-jefferson-airplane-singer-dead-at-74-20160131
KUIK reported the death of Signe Toly Andersen on Monday morning. I am a bit surprised that it took so long for the story to reach the press. Some other sources are citing chronic obstructive pulmonary disease as the cause of death.
