I think she meant they recorded one vocal (which may be the case, it could have been quite a long one) and all those alternate versions are remixes and other instrumentals. I've got all the I Can't Waits (that haven't been taken down) on my youtube channel if there's some you haven't heard.
I'll probably upload the Alice when I do my stuff for TOSOTM (which could be very soon, I'm finishing Street Angel right now.) If you want to download anything I've posted (other than the one original song that's on there) I recommend this site. https://keepvid.works/?url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DlbRiaQd76R0
