He first appears going to the gang how to make their music better but then Slash comes and makes fun of them for having an old man like Mr. Benson teaching them. Upset, he leaves and then the kids go to find him in his apartment building playing music on his saxophone. The Gang apologize for what slash has said and he goes with them in the band contest and he is presented by Fat Albert and the gang as he plays music with them.
- He is voiced by Gerald Edwards
- Lester seems similar to another character Uncle Monty from, "Shuttered Window" but had a different voice actor.
