"K Cera Cera", a presentation of The Red Army Choir by the K Foundation (Bill Drummond and Jimmy Cauty), was released as a limited edition single in Israel and Palestine in November 1993. The song was an amalgam of Jay Livingston/Ray Evans's "Que Sera, Sera (Whatever Will Be, Will Be)" and John Lennon/Yoko Ono's "Happy Xmas (War Is Over)". A rendition of "K Cera Cera" was incorporated into Drummond and Cauty's 1997 "23 minutes only" comeback performance at the Barbican Centre in London, part of their "Fuck the Millennium" campaign.
