Now well into his eighties, Delsener shows little sign of slowing down. At one point, the camera follows him as he ping-pongs across New York attending multiple concerts in one evening. His love for the work of putting on a show shines through as he drags the filmmakers through crowds and backstage so he can chat with artists and crew members. Interspersed with these present-day adventures are looks back on the highlights of Delsener’s career, reflecting his own intense nostalgia. It’s rare that a documentary so completely embodies the personality of its subject.
