The band is back!

Instead of playing in rundown bars, Uncle Joe's Band now sell out concert halls.

Prior to a tour in Japan, a letter arrives claiming one of the band members, Ian, is the father of an unnamed young woman, who coincidentally is the member of another band, Stygian Teal. In the hopes of identifying Ian's daughter, Uncle Joe's Band attends a Stygian Teal concert. Much to their surprise, they find not one, but four Stygian Teal band members, any of which could be Ian's daughter.

Meanwhile, as the band's namesake Uncle Joe, an aged deadhead, makes his way across North America during the '60s, '70s, and '80s, another Uncle Jo, Joji Kinsara, makes his way across the Japanese archipelago. Everywhere he goes, Joji leaves large painted haiku poems, which become noted works of art. In his travels Joji visits the Nagano Winter Olympics, starts an environmental revitalization of Mt. Fuji, and helps ensure that a young Masako Owada becomes a future empress.

As they journey through Japan, Uncle Joe's Band attempts to discern which young woman is Ian's daughter, how to deal with newfound fame, and what it takes to formulate a family.
