Here's...

A partial of "Rainbow", though it doesn't look like in three previous attempts full lyrics have been found. Cat's in the Cradle by Harry Chapin...

Last one I can't find much of. Maybe someone will have better luck, but the only "Jimmy Brown" that I can find is a variant on the million "Johnny be fair" songs, and another one by the name of Jimmy Brown, The Newsboy.

Hope this helps.
