ANN ARBOR — The University of Michigan marching band will perform a halftime show today — the 20th anniversary of the Sept. 11 terror attacks — that its director says will not only pay tribute to the lives lost and impacted that day, but also will be dazzling in its scope.

“It is going to be a pretty spectacular show,” said John Pasquale, director of Michigan marching and athletic bands.

During the 10-minute performance called “We Remember,” the 400 Michigan Marching Band members will carry a light — either a high-powered flashlight, a glowing orb, an illuminated umbrella or something else. Of those, 275 marchers will spin flags, twirl batons and play instruments.
