"The Hallowe'en concert was supposed to promote my new album."
-- Celestina Warbeck (DP4)
Celestina Warbeck, who was disappointed by the Ministry of Magic's new Hallowe'en restrictions, was hoping to sing this at a large open air concert on Hallowe'en. She and her backing group of banshees were also looking forward to the opportunity of "letting their hair down" onstage (DP4).
By the time the album was released the name seems to have been shortened to "You Stole My Cauldron But You Can't Have My Heart". It became a "massive global hit" for her (Pm).
Although the date printed on the Daily Prophet Newsletter DP4 is 1 October 1999, the timeframe for that event is 1992-1993.
