Battle of the Bands

S1 E11: The Naked Brothers Band and a rival band, the L.A. Surfers find themselves at the center of a heated battle of the bands for a charity event.  Even more heated is the battle for Rosalina's heart between Nat and the lead singer of the L.A. Surfers, Bobby Love.  Bobby is self assured, older than Nat and a dreamboat.  Rosalina falls hard and all of Nat's attempts to win her back result in disaster, even leading Rosalina to threat quitting the Naked Brothers Band.  When Nat discovers that Bobby is just using Rosalina to get to the Naked Brothers Band, he has to find a way to tell her without further alienating her.
