The show must and does go on, as Lady Gaga proved last weekend when she was struck in the head by a pole and kept on rocking during a performance in Auckland, New Zealand.
Gaga briefly left the stage before returning to perform another 16 songs, telling the audience, "I want to apologize, I did hit my head and I think I may have a concussion. But don't you worry, I will finish this show."
Videos of the incident show a male dancer accidentally hitting Gaga in the head with a metal set piece while taking it off the stage. Gaga, who was performing "Judas," briefly staggered and rubbed her head before walking off the stage. She was back a short time later.
Tara Savelo, the singer's make-up artist, tweeted about the incident on Sunday: "Gaga has a concussion but she is going to be okay. She wants u to know she loves u. I'm taking care of her. Can't believe she finished the show."

Just as Sugarland's Jennifer Nettles and Kristian Bush were about to take the stage at the Indiana State Fair last August, a powerful storm blew through the area and a huge gust of wind ripped down the stage scaffolding. Seven people that were killed, dozens more were injured. Numerous victims of the stage collapse filed a massive civil lawsuit on Nov. 22 claiming Sugarland and the companies involved with the construction of the stage were negligent and contributed to the accident. Sugarland has denied all accusations against the band, saying it had nothing to do with the stage's construction. In a statement to ABC News in February, Sugarland's manager Gail Gellman said, "Sadly when a tragedy occurs, people want to point fingers and try to sensationalize the disaster. The single most important thing to Sugarland, are their fans."
Marie Osmond suffered an accident of a different kind. During a March performance on a Bahamas cruise ship, she laughed so hard after an audience member's question that she peed on herself -- and the stage. Unashamed, Osmond exclaimed, "I just peed my pants! Oh ship!" She then used her dress to mop up the spot where she had her accident until someone brought her paper towels. Doubled over with laughter, her brother Donny Osmond told the audience, "We promised you an experience. You got it!"
At the 2010 Grammy Awards, singer Pink showed Cirque-du-Soleil-type skills when she performed a trapeze act while singing "Glitter in the Air." Trying a similar move in July that year during a concert in Nurnberg, Germany, Pink fell out of her harness and hit a metal barricade. She was immediately rushed to the hospital, where she later tweeted, "I am so so so sorry to end the show that way. I am embarrassed and very sorry. Getting xrays. I hope it at least looked cool!!!" Later she explained on Twitter that she, "didn't get clipped in2 harness correctly, drug me off stage, fell in2 barricade " Amazingly, the singer suffered no broken bones, just serious soreness.
"Love in an Elevator" just does something weird to Steve Tyler. In 2009, the Aerosmith frontman fell off stage while performing the song in South Dakota and had to be airlifted to a local hospital after suffering minor head, neck and shoulder injuries. The following year, it happened again in Toronto. Fortunately for Tyler, he emerged unscathed the second time around and was helped back on stage by fans and Aerosmith guitarist Joe Perry. Living it up when he's going down, indeed.
Jimmy Buffett's 2011 fall off a concert stage in Sydney, Australia, was made all the more ominous by the line he sang before taking a tumble: "It's been a lovely cruise, I'm sorry it's ended." Luckily, that wasn't last call for the "Margaritaville" singer. Buffett spent a night in the hospital after being knocked unconscious and was released the following day in good spirits, according to hospital staff.
Bret Michaels took a big blow to the head while performing at the 2009 Tony Awards. As the Poison frontman walked off stage, he was hit by a piece of scenery that knocked him to the ground. Photos of his fractured nose and busted lip went viral online, and Michaels later sued the Tonys claiming that the accident forced him to cancel scheduled Poison concerts and contributed to a life-threatening brain hemorrhage he suffered 10 months later. In May, Michaels settled with the Tonys and all the parties named in the lawsuit for an undisclosed sum of money.
