The one who sounded like they recorded onto an 8-track is me.

Not my best performance either but I tried.
Seriously, though:
Malte does the first part alone; then I join him. Then Sapphireraptor takes over. Malte sings about the dreams, then he and Sapphire join, and I join so we have a trio. Instrumental bridge. Malte on lonely, then Sapphire, then Malte, then me, then Malte finishes.
