The Predators then tied it when Bobby Butler rushed in for a rebound score with 3½ minutes remaining, beating Corey Crawford high into the net.
"The effort to compete was there," Halischuk said. "We did all the good things, but unfortunately didn't get the two points."
The dramatic finish came after a crazy first period that featured a pair of goals for each team.
Keith's third of the season and first in 14 games put Chicago in front. But the Predators responded with a pair of rebound scores. First, Halischuk poked the puck through Crawford's legs to tie it at 1 at 6:31. Then Butler drove to the net and Henderson slammed it home in a scrum in front of the goal.
"I was fortunate to get the goal there and help the team out, but it was just an amazing experience for me," Henderson said. "I was just by myself, and knew I got a stick on it. I was just ecstatic."
Nashville's lead didn't last very long, with Saad tying it at 2 with his 10th of the season at 13:36. Saad, a contender for the Calder Trophy awarded to the NHL's top rookie, has seven goals and 15 assists in his last 24 games.
