David Gilmour has shared a documentary detailing alleged antisemitism from his former Pink Floyd bandmate Roger Waters, adding one other chapter to the decades-long feud between the musicians.

Gilmour retweeted a post in regards to the documentary, entitled The Dark Side of Roger Waters, from the Campaign Against Antisemitism, which produced the report. Within the video, BBC journalist John Ware interviews Norbert Statchel, Waters’ former saxophonist, and Bob Ezrin, the music producer who helped helm Pink Floyd’s The Wall. Each men, who’re Jewish, recalled experiences wherein Rogers said things that were antisemitic.

Statchel retold an instance wherein Rogers imitated a stereotypically poor Polish woman as a reference to his Jewish ancestors, and one other wherein the bassist expressed outrage at a restaurant serving “Jew food.” Erzin recalled Waters describing Bryan Morrison, Pink Floyd’s manager on the time, as a “fucking Jew.” The report also unearths a 2010 email wherein Waters suggests using Jewish imagery and slurs as a part of his stage design for an upcoming show.

Gilmour didn’t add a comment when he reposted the video, but he’s spoken out against Waters’ antisemitic remarks before. In February, the guitarist’s wife, Polly Samson, denounced Waters as “antisemitic to [his] rotten core,” in addition to “a Putin apologist and a lying, thieving, hypocritical, tax-avoiding, lip-synching,misogynistic, sick-with-envy, megalomaniac.” Gilmour shared that tweet as well, calling Samson’s claims “demonstrably true.”

For his part, Waters has dismissed the documentary as “a flimsy, unapologetic piece of propaganda that indiscriminately mixes things I’m alleged to have said or done at different times and in numerous contexts, in an effort to portray me as an antisemite, with none foundation actually.”

Earlier this yr, Waters performed in a dressing up featuring a leather jacket, gloves, an armband, and a rifle that appeared to resemble that of a Nazi SS soldier, prompting German police to launch an investigation into “suspected incitement.” Soon after, the town of Frankfurt canceled a scheduled concert by the performer at Festhalle, a venue that was once a Jewish detention camp, citing the town’s partial ownership of the venue. The concert was rescheduled for a later date and was promptly crashed by a protestor.
