A Cauldron Full of Hot, Strong Love
From UnknowableWiki
A Cauldron Full of Hot, Strong Love is a jazzy song by Celestina Warbeck. Arthur and Molly Weasley danced to it when they were eighteen. They, along with most of their family and Fleur, Harry, and Remus, listen to it again on Christmas, 1996 (HBP16).
Oh, come and stir my cauldron, And if you do it right, I'll boil you up some hot strong love To keep you warm tonight.
