Excerpt:
But by the time the album came out, Anderson had given birth to her first child and she left after a farewell concert at the Fillmore in October 1966....
“You have to look at the priorities in your life, the reality in your life,” Anderson told radio station KGON in Portland in 2011, remembering the ordeals of bringing her baby on tour. “I had to wait in the San Francisco airport in July of 1966 for 36 hours before we got on the airplane and flew to Chicago. All the diapers were gone.”
“I don’t regret having left,” she added.
Anderson was a footnote in the Airplane’s history, but was regarded with respect and affection by fans and stayed in touch with Kantner, Balin and other band members with whom she performed on occasion over the following decades....
Airplane guitarist Jorma Kaukonen wrote on his blog that Anderson was “our den mother in the early days of the Airplane” a voice of reason for “our dysfunctional little family.” Balin, writing on Facebook, imagined that she and Kantner “woke up in heaven and said ‘Hey what are you doing here? Let’s start a band.’”
