Face of the Band: Grace Slick tended to get the most attention for Jefferson Airplane; Mickey Thomas took over the role when he joined Jefferson Starship.
Fanon Discontinuity: The first Jefferson Starship album (which was actually credited to "Grace Slick/Paul Kantner/Jefferson Starship" rather than the band as a unit) is often ignored in favour of the second album, Red Octopus, which was credited to the band as a whole, featured the return of lead vocalist Marty Balin, included their biggest hit (the ballad "Miracles") and remains the only number one album by any version of the group.
Jumped the Shark / Broken Base: Despite being on some wildly popular hit singles, the advent of Mickey Thomas is not remembered pleasantly by longtime fans.
