I know this is a weird post, but here it goes. I was watching a tv show called millionare matchmaker, and this one guy said this was the building janis joplin and mamas and papas lived at. I didn't catch the name of the building, so I thought someone in here would know. I think its the same building they all took acid trips at that Mama Cass Showed up also, but could be wrong. Many thanks and sorry for such a odd request. I just saw the program and when he said "Mamas and Papas", well, my head gears started turning.
Thanks for any information if possible.
