There is no Lauren Mayberry, only ZVVL

I just out that the band Chvrches have a song called "Zuul", except, just like their band name, the song is spelled "Zvvl".  So...when I was looking to see the contents of the RECOVER E.P., I was like "WHAT?!" then moved on...I thought maybe it was some African or German word that English speaking non-multi-linguals aren't meant to pronounce...but then I saw an interview with Lauren Mayberry and Ian Cook where Lauren Mayberry cited a fan yelling out "There is no Dana, only Zuul!", and judging by the wording of the answer (?; not sure who compiled the questions...), I'm assuming that the title of the song was indeed taken from GHOSTBUSTERS.

Rock on, CHVRCHES!
