Lady Gaga revealed that she was working on another song that didn't end up on MAYHEM before starting "Abracadabra":
"It was like, a mid-tempo thing. But then Cirkut was like, 'I've got something I've been working on, I wanted to play it for you.' [...] We just stopped everything that we were doing. Andrew [Watt] was like 'that could be a hard beat to write over, cause it's so busy.' And I was like, 'watch me'."
Lady Gaga revealed that her part in Wednesday season 2 came after she got a phone call that the show was looking for music:
“I immediately had a song in mind called ‘The Dead Dance,’ and I had started working on it. But once I knew it was going to be for Wednesday, I decided that I was going to work on it even more, and I made it extra special for the show. To me, when you know that music and pop culture and Tim Burton all come together with this cast, that’s a very special recipe.
After that happened, they asked me if I wanted to be on the show, and I said, ‘Absolutely.’”
