A Cauldron Full of Hot, Strong Love

"A Cauldron Full of Hot, Strong Love" was a jazzy song performed by Celestina Warbeck. Arthur and Molly Weasley danced to it when they were eighteen, and, with their family, they listened to it again on Christmas 1996 on the Wizarding Wireless Network.

Lyrics
The song's lyrics include:

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
