In Texas, Joplin adopted a healthier and more straight-laced lifestyle and was briefly engaged. When the relationship ended, she returned to San Francisco in 1966 and joined the band Big Brother and the Holding Company. During this time, Joplin apparently moved often and had several apartments in the city.
By 1967, however, Joplin was sharing an apartment with her friend Linda Gravenites at #3 122 Lyon Street. Of all of Joplin's rumored addresses in the city, the Lyon Street apartment is the only one that appears on official documentation. Her California driver's license, issued in August of 1967, lists her address as 122 Lyon Street, #3. Country Joe McDonald had a brief relationship with Joplin and lived with her in the Lyon Street apartment for a few months.
The building was put up for sale in 2014 with a list price of $1.7 million.
