On Thursday, Stone Temple Pilots’ seminal debut album Core turned 30. On Thursday night, Scott Weiland’s previously unreleased cover of John Lennon and Yoko Ono’s “Happy Xmas (War Is Over)” also dropped — it’ll appear on the Deluxe edition of Weiland’s The Most Wonderful Time Of The Year, out November 4. As a press release notes, the 2011 10-song collection will be expanded with four unreleased recordings for its vinyl debut — it’ll be the first posthumous music to be released from the Weiland vault. (The Stone Temple Pilots singer died in 2015 at 48.)
