In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In writing Young Modern, Johns tried to make the music sound very simple, despite a complex musical structure. The lyrics were written after the music was created, sometimes as late as the day of recording. As Johns dreads writing lyrics, he suggested that the band could produce an instrumental album at some stage in the future. Johns is the band's primary songwriter, and notes that while Joannou and Gillies do not have significant influence on what he writes, they are key to the band's overall sound. For that album, Hamilton co-wrote four songs with Johns including the APRA Award-winning "Straight Lines". Joannou believed that Young Modern was simpler than Diorama but "still as complex underneath with simple pop song elements". He said that much of the band's success resulted from trying to push themselves harder in recording and writing. Self-producing has allowed the band to do so without the pressures of a record label.Gillies notes that Silverchair will often "run the risk of losing fans" with their work, and this was evident in the changes in musical direction in Diorama and Young Modern. However, he described this as a good thing, describing the fact "that we haven't been pigeonholed, and people really don't know what to expect" as one of the attractive elements of the band. Despite the ups and downs of success at a young age, Gillies says the band "appreciate what we've achieved and what we've got" in their careers. The band have received six APRA Awards with Johns winning three songwriting awards at the 2008 ceremony.

Ex Output:
What is the name of the band John's suggested could produce an instrumental album at some stage in the future?

Passage: The frustration at #1 Record's obstructed sales contributed to tension within the band. There was physical fighting between members: Bell, after being punched in the face by Hummel, retaliated by smashing Hummel's new bass guitar to pieces against the wall. Hummel took revenge at a later date: Finding Bell's acoustic guitar in the latter's unattended car, he repeatedly punched it with a screwdriver. In November 1972, Bell quit the band. When work continued on songs for a second album, Bell rejoined, but further conflict soon erupted. A master tape of the new songs inexplicably went missing, and Bell, whose heavy drug intake was affecting his judgment, attacked Fry's parked car. In late 1972, struggling with severe depression, Bell quit the band once more, and by the end of the year Big Star disbanded.
After a few months Chilton, Stephens, and Hummel decided to reform Big Star, and the three resumed work on the second album. The title chosen, Radio City, continued the play on the theme of a big star's popularity and success, expressing what biographer Robert Gordon calls the band's "romantic expectation". As Hummel put it,
This was probably pretty lame, but in those days putting any word in front of the noun "city" to sort of emphasize the totality and pervasiveness of it was just a way of talking people had. If someone suggested going to a store but you had gotten a bad deal there you might say, "Oh no, that place is 'rip off city'." Calling an LP Radio City would be kind of wishful thinking. I mean we hoped it would be played on the radio a lot, making it "radio city". Of course it didn't pan out that way... Stephens recalled: "Radio City, for me, was just an amazing record. Being a three-piece really opened things up for me in terms of playing drums. Drums take on a different role in a three-piece band, so it was a lot of fun. [...] Radio City was really more spontaneous, and the performances were pretty close to live performances."Although uncredited, Bell contributed to the writing of some of the album's songs, including "O My Soul" and "Back of a Car". Shortly before the album's release, Hummel left the band: judging that it would not last, and in his final year at college, he elected to concentrate on his studies and live a more normal life. He was replaced by John Lightman for a short tenure prior to the band dissolving.

Passage: After a tour of the UK performing Dark Side, Pink Floyd returned to the studio in January 1975 and began work on their ninth studio album, Wish You Were Here. Parsons declined an offer to continue working with them, becoming successful in his own right with the Alan Parsons Project, and so the band turned to Brian Humphries. Initially, they found it difficult to compose new material; the success of The Dark Side of the Moon had left Pink Floyd physically and emotionally drained. Wright later described these early sessions as "falling within a difficult period" and Waters found them "tortuous". Gilmour was more interested in improving the band's existing material. Mason's failing marriage left him in a general malaise and with a sense of apathy, both of which interfered with his drumming.Despite the lack of creative direction, Waters began to visualise a new concept after several weeks. During 1974, Pink Floyd had sketched out three original compositions and had performed them at a series of concerts in Europe. These compositions became the starting point for a new album whose opening four-note guitar phrase, composed purely by chance by Gilmour, reminded Waters of Barrett. The songs provided a fitting summary of the rise and fall of their former bandmate. Waters commented: "Because I wanted to get as close as possible to what I felt ... [that] indefinable, inevitable melancholy about the disappearance of Syd."While Pink Floyd were working on the album, Barrett made an impromptu visit to the studio. Thorgerson recalled that he "sat round and talked for a bit, but he wasn't really there". He had changed significantly in appearance, so much so that the band did not initially recognise him. Waters was reportedly deeply upset by the experience. Most of Wish You Were Here premiered on 5 July 1975, at an open-air music festival at Knebworth. Released in September, it reached number one in both the UK and the US.

What is the first name of the person who no longer wanted to work with Pink Floyd?
