Salad Days.

Set in a small town suburb, a pathological lying teen, Max, tries to win over his crush Lindsey by inviting her to a concert that has yet to exist. After his band band mates suddenly quit and Max realizes his inability to write music, he is left with deceptively recruiting his broken hearted friend, Greg, to write for him. But when Greg tries to to get back with his girlfriend and realizes what Max has done to him, they must put aside their differences in order to push their music careers and relationships forward.
