And Yesterday will be a dreamscape. I'm still not sure whether or not to make Help! (the song) a dreamscape but I'm leaning towards doing it just because it would make things more interesting.
Her Majesty would make the perfect dreamscape for Yesterday.
BlackBird would also work with Her Majesty.
I'm pulling that you do Help! Though, or White Album Disc 2 (TWO [DOS])
