Task: Question Answering
Input (English): Passage: Gilmour recorded his second solo album, About Face, in 1984, and used it to express his feelings about a variety of topics, from the murder of John Lennon to his relationship with Waters. He later stated that he used the album to distance himself from Pink Floyd. Soon afterwards, Waters began touring his first solo album, The Pros and Cons of Hitch Hiking. Wright formed Zee with Dave Harris and recorded Identity, which went almost unnoticed upon its release. Mason released his second solo album, Profiles, in August 1985.Following the release of The Pros and Cons of Hitch Hiking, Waters publicly insisted that Pink Floyd would not reunite. He contacted O'Rourke to discuss settling future royalty payments. O'Rourke felt obliged to inform Mason and Gilmour, which angered Waters, who wanted to dismiss him as the band's manager. He terminated his management contract with O'Rourke and employed Peter Rudge to manage his affairs. Waters wrote to EMI and Columbia announcing he had left the band, and asked them to release him from his contractual obligations. Gilmour believed that Waters left to hasten the demise of Pink Floyd. Waters later stated that, by not making new albums, Pink Floyd would be in breach of contract—which would suggest that royalty payments would be suspended—and that the other band members had forced him from the group by threatening to sue him. He then went to the High Court in an effort to dissolve the band and prevent the use of the Pink Floyd name, declaring Pink Floyd "a spent force creatively." When his lawyers discovered that the partnership had never been formally confirmed, Waters returned to the High Court in an attempt to obtain a veto over further use of the band's name. Gilmour responded by issuing a carefully worded press release affirming that Pink Floyd would continue to exist. He later told The Sunday Times: "Roger is a dog in the manger and I'm going to fight him." In 2013, Waters said he had failed to appreciate that the Pink Floyd name had commercial value independent of the band members, and was wrong to have attempted to stop the others using it. 
Question: What is the first name of the person whose lawyers discovered that the partnership had never been formally confirmed?
Output (English): Roger.
