Bobby Brown performed at a Fourth of July concert in Atlanta on Saturday night, and an eyewitness tells ET that the show was a bit bizarre.

The troubled 46-year-old singer forgot lyrics to his own hit songs and was acting strangely, the eyewitness said. The show, which was attended by several of Brown's friends and family members, also featured other old-school hip-hop acts such as Juvenile, Tweet and Mint Condition.

Despite the fact that his daughter Bobbi Kristina now resides in a nearby hospice care facility -- where Brown visited her just days ago -- the singer did not mention her by name. He did, however, admit to being out of it while onstage.

"Hold on Atlanta. Atlanta, I can't hear y'all. I know it's a little early but god damn it. I probably know but one of you all up in here. Let's have some fun!" Brown said to the crowd between songs. "Yo, I was skipping songs and s**t… I feel like I have been up here for like two hours. Trust me I'm not gonna do anything that I don't do. I love giving a good show, you're all gonna get it."

After speaking with his bandmates before the next song, Bobby addressed the crowd again, saying, "I keep forgetting s**t right now. I'm in a different zone right now so you will all gonna have to excuse me if I just go somewhere else. Please join me 'cause it's going to be a great trip."

Like his late ex-wife Whitney Houston, Brown has struggled with drug and alcohol issues in the past. His friends and family have been concerned for his well-being ever since Bobbi Kristina was found unconscious in a bathtub on January 31.

His former New Edition bandmate Johnny Gill opened up to ET about his friend a few days ago, saying Brown's state of mind right now is, "in a nutshell, not good."

Gill also discussed Brown's love for his daughter, saying that although the two had been "estranged" for some time, they began to "rebuild" their relationship after Bobbi Kristina reached out to Brown on Father's Day several years ago.

Just this week, the family expressed outrage when they learned that someone had taken photos of Bobbi Kristina in the hospice facility and was shopping them around to media outlets. 

As of Sunday afternoon, there were no updates on Bobbi Kristina's condition. ET can report that a security guard at the hospice facility said things there had quieted down now that the Brown family has cut their visitor list in half since the photo scandal.
