Alvin's Studio - S1.E21

Dave's ready to rehearse a new song but the boys aren't (Alvin's playing with a yo-yo, Simon's reading, and Theodore's playing with a parakeet (George)). When Dave walks out on his boys (to play golf) following a heated argument about their new song, Alvin takes over and he tries to have his brothers perform a different song. In doing so, he begins to sound like Dave. After some time arguing with each other and the neighbor about how to yell Alvin, a large group of people congregate outside the house. Dave arrives to the pleasure of the boys and they sing his song.
