Paul Kantner died in January 2016. Grace Slick is still alive.
I saw the Jefferson Starship with Chris Smith, David Freiberg, Cathy Richardson, Paul Kantner, Donny Baldwin, and Jude Gold in 2014 at the
Narrows Center for the Arts, in Fall River, MA. The Narrows is a small venue night club that seats ~200 around small tables and church pews.
Cathy Richardson was AWESOME! Better than Grace Slick as MrsMac saw the Jefferson Airplane in her youth several times. The group played three sets with each one being about an hour long. I was exhausted when the concert was over.
Bummer. Hey, we are all getting old aren't we?
