The Zombies song was definitely interesting but I really like Moby Grape's song best. They are a band I've heard of but never heard. I wasn't surprised when I googled them to see that they were from San Francisco. I thought I detected Jefferson Airplane-like moments in this song.
Yes, Moby Grape were part of the San Francisco sound as Jefferson Airplane. Actually one of the guitarists and main songwriters of the group was Skip Spence, who was the drummer in the Airplane's debut album.
