I thought she was doing most of it out there at Skywalker, and at Morningwood. Prolly overdubs at Sony? But it didn't look like a studio setup. There was a video "machine room" adjacent to the one where the piano was.
For the record...I didn't meet Vanessa , but for me, I liked meeting a few Holics I never met before...seeing Holly there(glowing!!!) just warmed my heart.
