In some correspondence, I came upon a quotation of a phrase from what seems to be a piyyut composed by Rabbi Simon Schwab z"l, rabbi of Adas Jeshurun in Washington Heights (the "Breuer'sche") from 1958 until his death in 1995. I've tried to identify its source, without success.
The name cited for the piyyut is הזוכר מזכירין.
The phrase: זכור וספור בנאדך צרור, apparently an allusion to Psalm 56:9.
For those with with the gift of a long memory, this query may ring a bell. I posted a similar question almost twenty years ago, to no avail. I thought I'd try again and would be grateful for any help.
