The article text supplied for this page could not be retrieved in full — what was provided consists only of website navigation and menu elements (Music, Film, Travel, Art, News, Shop, Mailing List) rather than the actual body of the piece. As a result, no substantive information about the 1987 Pink Floyd album or Roger Waters' reported feelings of betrayal is available to summarise accurately.

Based on the headline alone, the piece appears to concern "A Momentary Lapse of Reason", the Pink Floyd album released in 1987 without Roger Waters, who had left the band the previous year. However, without the actual article content, specific quotes, context or details cannot be reliably confirmed or reported.
