I think the chorus of Dreams of Our Fathers comes straight from the old versions of Little Thing, but that's about as much musical savvy as I can muster
dreams of our father's bridge is the exact same as the chours of Little Thing/An Another Thing and the intro and outro of the old Raven. The rest of the song I think doesn't sound like or has to do with Little Thing, ect. The bridge is the same, though, and he even still sings, "Rain on my head," just like Little Thing.
Watching DMB's songs evolve and grow is one of the reasons I enjoy their music, especially seeing the band live. There are not many bands today that you could give you this experience.
Peace,
