Bass player Nick Beggs, already the group's main backing singer, took over lead vocal duties, and also wrote the lyrics.

It is the final album to-date to feature founding drummer Jez Strode. The album also marked the first time Nick Beggs used the Chapman Stick on a recording.

Example Input: Question: How many different directors did Prada work with in 1976 and 1977? Passage:When Jaya Prada was a teenager, she performed a dance at her school's annual function. A film director in the audience offered her a three-minute dance number in the Telugu film Bhoomi Kosam. She was hesitant, but her family encouraged her to accept it. She was paid only 10 rupees for her work in the film, but the rushes of those three minutes of film were shown to the major figures of the Telugu film industry. Major filmmakers offered her starring roles in quality films, and she accepted them. She became a huge star in 1976 with major hit films. Director K. Balachander's black-and-white film Anthuleni Katha (1976) showcased her dramatic skills; K. Viswanath's color film Siri Siri Muvva (1976) showed her playing a mute girl with excellent dancing skills; and her title role as Sita in the big-budget mythological film Seetha Kalyanam confirmed her versatility. In 1977, she starred in Adavi Ramudu, which broke box office records and which permanently cemented her star status. The song "Aaresukoboyi Paresukunnanu" performed by Prada and co-star N.T. Rama Rao became a mass hit. Important filmmakers were casting her and repeating her in their films. Filmmaker Vijay introduced her to Kannada cinema in his 1977 super-hit movie Sanadi Appanna alongside Kannada matinee idol Raj Kumar. The movie is also known to be the only movie to feature shehnai rendition by Ustad Bismillah Khan. Jaya Prada repeated her successful pairing with Rajkumar in films such as Huliya Halina Mevu (1979), Kaviratna Kalidasa (1983) and Shabdavedhi (2000). In 1979, K. Balachander repeated her in the Tamil film Ninaithale Inikkum opposite Kamal Haasan and Rajinikanth in which she played a terminally-ill patient. She continued to act in more films in Telugu opposite actors such NTR, ANR, Krishna, Krishnam Raju and Sobhan Babu throughout the 70s and 80s. K. Viswanath remade Siri Siri Muvva (1976) in Hindi as Sargam, introducing Jayaprada to Bollywood in 1979. The film was successful and she became a star there as well. She earned her first Filmfare nomination as Best Actress but couldn't capitalize on her success since she couldn't speak Hindi.

Example Input: Question: How old was King Henry IV when the Saxon Rebellion began? Passage:After the deposition of the Saxon duke Henry the Lion in 1180, the Regenstein counts were temporarily arrested by the forces of Emperor Frederick Barbarossa, but were reconciled with the Hohenstaufen monarch soon after. After a lengthy feud Heimburg Castle, built about 1170 by King Henry IV and soon after devastated during the Saxon Rebellion, was acquired by the Regenstein counts in the early 14th century. The Regenstein-Heimburg branch re-united the Regenstein and Blankenburg estates in 1343, under the rule of the most renowned Count Albert II (1310–49), who since the 1330s was frequently in dispute with the leaders of the surrounding estates like the Halberstadt bishops and the Abbesses of Quedlinburg; he was finally assassinated by the henchmen of Bishop Albert II of Halberstadt. These tales were romanticised in the ballad The Robber Count () by Gottfried August Bürger, melodized by Johann Philipp Kirnberger and the novel of the same name by Julius Wolff.
