The Grass Roots
Producers/songwriters P. F. Sloan and Steve Barri heard the demo and liked it. They needed new band members for a folk-rock group that they had created in 1965. The 13th Floor lost their bass player to the military draft during this time, and quickly recruited Rob Grill, changing the band's name to the "Grass Roots" for prior name recognition. The group went straight to the Top 10 with the song "Let's Live for Today" in 1967 and toured the United States. Iconic hit songs such as "Midnight Confessions" cemented the group's standing as major contributors to the rock-music scene.
The Grass Roots had top songwriters offering their best songs to them and wrote many songs themselves. For their major songs, music on the recordings was played by the LA studio musicians known as the Wrecking Crew. Bratton co-wrote the songs "Beatin' Round the Bush", "No Exit" and "Hot Bright Lights", and self-composed "Dinner for Eight" and "House of Stone". He sang lead vocals on "This Precious Time" and "Dinner for Eight". Bratton played with the group on its albums Let's Live for Today, Feelings, Golden Grass (a compilation) and Lovin' Things. Three of the albums charted, and Golden Grass received a gold record certification. He took part in ten of the group's singles, eight of which charted; "Midnight Confessions" received a gold record certification.
The Grass Roots played at the Fantasy Fair and Magic Mountain Music Festival on Sunday, June 11, 1967, during the "Summer of Love" as their top-ten hit "Let's Live for Today" was hitting the airwaves. Though the music festival occurred before the Monterey Pop Festival, it was not filmed as was the latter festival (see List of electronic music festivals). On Sunday, October 27, 1968, the group played at the San Francisco Pop Festival and then played at the Los Angeles Pop Festival and Miami Pop Festival in December as the top-ten hit "Midnight Confessions" was becoming popular.
In April 1969, Bratton became frustrated by Dunhill's refusal to allow the band to write its own songs and play the instruments on its records (although the members did play alone at concerts). After a disastrous appearance at the Fillmore West in April 1969, Bratton was asked to leave the band.
