Douglas accepted Nesmith's offer, and joined the Monkees in the studio, first to create a new single with all four Monkees playing. It couldn't be released because of a publishing restriction imposed by
Screen Gems (who both produced the Monkees series and controlled their
music publishing). Douglas's next Monkees project was their
Headquarters album. Recorded over six steady weeks of sessions at the RCA Studios in Hollywood,
Headquarters was the first album to feature the Monkees playing on every track. Douglas contributed a song, "Forget That Girl", and joined them on bass guitar in the studio. The album was released in the spring of 1967, and began a steady climb up the charts, eventually reaching #1 on Billboard's album chart, but was displaced by the Beatles' ''
Sgt. Pepper's Lonely Hearts Club Band''. No singles from
Headquarters were issued in the United States, but a non-album song from the same sessions, "
The Girl I Knew Somewhere", reached the top 40 as a B-side. Douglas produced the hit single "
Pleasant Valley Sunday" (written by
Gerry Goffin and
Carole King), which featured Douglas on bass and an innovative guitar intro composed by Douglas and played by Nesmith. Douglas produced the next Monkees' album,
Pisces, Aquarius, Capricorn, & Jones, Ltd., on which he also played bass. Unlike
Headquarters, it was done in several different studios around the U.S. between Monkees tour dates. Douglas also introduced members of the Monkees to new songwriters, including
John Stewart, who wrote "
Daydream Believer", which would become their second-biggest all-time single and was included on the 1968 album
The Birds, The Bees & The Monkees. Douglas also introduced the band members to Harry Nilsson, who played them a selection of his original songs, and became friends with the band. One of the songs, "Cuddly Toy", was covered by the Monkees, and featured on both the
Pisces album and an episode of their TV series. Douglas has been quoted as saying, "I like to think I gave Harry his big break, which resulted in a record deal with RCA." Douglas was pleased to have made hit records with the Monkees, but was disappointed that they weren't able to erase the common misconception that The Monkees weren't actually musicians, and that the press took little notice of their accomplishments. ==The Turtles, revisited==
