The opening theme is titled "Bouken Desho Desho?" (It's an Adventure, Right? Right?). The ending theme is titled "Hare Hare Yukai" (Sunny, Sunny Day). The insert dong that Haruhi sings at her school concert is called "GOD KNOWS." All were sung by Aya Hirano, Haruhi's seiyuu/voice actress, while Mikuru/Yuko Goto and Yuki/Minori Chihara join in for Hare Hare Yukai.
The song God Knows is from The Melancholy of Haruhi Suzumiya. I hope that helped!
