Heres one I wrote, about Gandalf, after frodo wrote the lament of Gandalf. You repeat the last line of his poem like this. He stood upon the bridge alone and fire and shadow both defied his staff was broken on the stone in khazadum his wisdom died. Now here is my part Down they fell through fathoms deep, Gandalf and the shadow flame, up they climbed the endless stair so steep then upon the mount he smote Durin's Bane. Through this deed he now had earned, new tilte and apparel bright, now longer Gandalf the grey old and learned, but Gandalf the shining white. I wrote that because after Gandalf showed back up the before part seemed incomplete.
