Document 4: People Like Us (The Mamas &amp; the Papas album): People Like Us is the fifth and final studio album released by The Mamas & the Papas, in November 1971 (three years after the group originally split). This album came to be because the former members of the group were still under contract with Dunhill Records. The group had originally been signed to the label when it was run by their original producer Lou Adler, but by 1971, Dunhill's distributor, ABC Records, had purchased the label and discovered the clause in the group's original contract. According to their contract, the group had to produce one more album, or else be in breach of contract and subject to possible fines. Although the album has some memorable songs, it is considered a disappointment by fans and critics. Nevertheless, the album sold moderately well. (#84 on the Billboard Pop Albums Chart.) It was produced by John Phillips. Michelle Phillips wrote later in the liner note of a Mamas & Papas CD compilation that the album "sounded like what it was, four people trying to avoid a lawsuit".

Document 7: Dolenz, Jones, Boyce &amp; Hart: Dolenz, Jones, Boyce & Hart is an album by the group of the same name, released in 1976.

Dolenz and Jones had been members of 1960s pop group/band The Monkees while Boyce and Hart had written many of the group's biggest hits such as "Last Train to Clarksville" and "(Theme from) The Monkees". As such, several publications, such as Allmusic, consider the album to be a Monkees-reunion album. Most of the musicians that appear on this album were featured on Monkees albums in the past. A majority of the vocals are done by Dolenz and Jones ("Right Now", "I Remember The Feeling", "You And I") with Boyce And Hart contributing backing vocals and the occasional lead vocal such as Hart's on "I Love You [And I'm Glad That I Said It]". Although the album failed to make much of an impact when originally released, renewal of interest in The Monkees led to its reissue on compact disc years later. The group was called Dolenz, Jones, Boyce & Hart because they were legally prohibited from using The Monkees name. Former Monkees members Michael Nesmith and Peter Tork were also invited to join the group, but they both declined. Peter Tork joined 'Dolenz, Jones, Boyce, & Hart' onstage for a guest appearance on their concert tour on July 4, 1976 in Disneyland.
