I didn't know this: the Tears For Fears song "Shout" was written after member Roland Orzabal had done primal scream therapy. (Though, as Orzabal himself says, there's more to it than that.)

Speaking of "Shout": sighted once, written into the crevice between bathroom tiles: Shout, shout, let it all out, these are the things I can do with grout...
