Appearing this afternoon at a Pentagon near you, Gary Sinise will be performing with the Lt. Dan Band as part of the America Supports You program, a “nationwide initiative to showcase and communicate Americans’ support of the Armed Forces,” according to Reuters. We at DCist wish we were joking with the band name, but it really is called the Lt. Dan Band. For those of you not familiar with Lt. Dan, he was Forrest Gump’s alcoholic, paraplegic pal who later made peace with the Vietnam War and his injuries. With our newfound knowledge of the Lt. Dan Band, we wonder if other bands could pop up with names inspired by supporting characters in Robert Zemeckis films. The George McFly Experience? Could be big for Crispin Glover. Or what about Baby Herman’s Hermits? Anyway, it sounds like this performance might be closed off to the public (it’s in the Pentagon Courtyard). But don’t fear, we’ll let you know as soon as tickets for the 9:30 Club show go on sale (password = CSI:NY).
