Almost every show on the 18-month tour has sold out, including two at the Beacon Theater in New York, four at the Sydney Opera House, and 32 straight shows across the U.K., where Dan lives. Tickets for today's show cost between $63.50 and $150, and it's sold out. The glass doors lead in to a 5,000- seat theater in Wallingford, Connecticut, a half hour from the closest city. Some of them carry pictures or posters of Dan. The kids-it's almost all boys-run circles around each other to pass the time, or they twirl their fidget spinners, or they plead with their parents for a phone to play with.

They're already here, standing outside in a raggedy line that begins at the locked glass doors and ends somewhere near the parking lot.
