Watch this exclusive look at Gary Sinise & the Lt. Dan Band performing a live concert for the troops at Naval Base Ventura back in March! With over 3,000 in attendance, it was a night of jubilation, gratitude, dancing, and a whole lot of Rock & Roll. Gary's good friend and GSF Ambassador Joe Mantegna made a special appearance, joining Gary and the band on stage! Honor. Gratitude. Rock & Roll. That’s the mission of every Lt. Dan Band concert.
