In July 1966, Anderson informed Bill Graham that she was quitting the band after a series of shows they were playing in Chicago, realizing that bringing her newborn child, with then-husband Jerry Anderson, on the road was not feasible. Graham, however, asked her to stay with the band through the October shows at the Winterland Ballroom in San Francisco, to which she agreed. This gave the band time to search for her replacement, eventually choosing Grace Slick after Sherry Snow declined their offer. Allegedly there were other factors, such as the hostility of other band members towards her husband.
