Alvin tells a girl he wants to impress that they are famous and will be starring in a rock concert. Seeing as The Chipmunks are not lined up to perform in the concert, Alvin creates a plan to sneak in to talk to the producer. After Alvin lies to Mr. Winters and Dave, the boys carry 100,000 fan letters they wrote for the producer to the studio. Their plan is foiled and the boys end up dropping into the rock show by mistake, much to Dave's surprise. Instead of Alvin impressing Julie, Theodore mistakenly does.
