My Dad's Infinite Songs

Tetta Mamiya dreamed of making his recording debut as a singer, but he gave up that dream for his son Yuta. Now, Tetta runs a musical instrument shop in Yokosuka. He is a humorous and popular man, who occasionally sings on a local stage in Yokosuka. One day, Tetta is diagnosed with Alzheimer's disease. The only things that keeps him cognizant is his son Yuta, his wife Ritsuko, his friends and the music that he loves. The only time Tetta returns to his true self is when he sings his favorite songs.
