A Momentary Lapse of Reason is the thirteenth studio album by the English rock band Pink Floyd, released in the UK on 7 September 1987 by EMI and the following day in the US by Columbia Records. It was recorded primarily on the converted houseboat Astoria, belonging to the guitarist, David Gilmour. A Momentary Lapse of Reason was the first Pink Floyd album recorded without founding member Roger Waters, who departed in 1985. The production was marred by legal fights with Waters over the rights to the Pink Floyd name, which were not resolved until several months after release. It also saw the return of founder member Richard Wright, the group's keyboardist who had been fired by Waters during the recording of The Wall. Wright returned as a session player. Unlike most of Pink Floyd's studio records from the preceding decade, A Momentary Lapse of Reason is not a concept album. It includes writing contributions from outside songwriters, following Gilmour's decision to include material once intended for his third solo album. The album was promoted with three singles: the double A-side "Learning to Fly" / "Terminal Frost", "On the Turning Away", and "One Slip".
