Here is the notes on the back up real singer from SeeU's past revisions of her page.

The file that proved there was a real singer is now gone, however.

Avanna had a real singer in her "only time" demo, though it was not used in anything too serious (they used the instrumental version, of which the original singer's "dee-da-day" notes was in it). Whereas with SeeU they literally sing both at the same time throughout a lot of the song.
