Rod Stewart stops concert to use oxygen tank

Rod Stewart has been forced to pause mid-concert to use an oxygen tank after nearly fainting on stage.

As shown in a video obtained by TMZ, the 81-year-old could be seen doubling over during his concert in Utah on Saturday night, and grabbing onto surrounding instruments to stay upright as he finished the song.

He then waited for staff to bring an oxygen tank to the side of the stage and took a few deep breaths from it before returning and addressing the crowd.

"The show must go on," he said, as he informed them that he "nearly f**king fainted" and tried to do a little dance.

The rocker then asked fans if he could sit down. He finished the show sitting in a chair.

It's not the first time his One Last Time world tour has been marred by health issues.

Earlier this month, the Maggie May singer announced that a number of his residency performances in Las Vegas were being rescheduled as he recovered from the flu.

He then cancelled four shows and postponed two more the following week.

He even drew criticism after cancelling his concert in California, only to share photos of himself getting on a plane to watch the Scotland World Cup game in Boston just hours later.

At the time, Stewart's team shared a statement on his Instagram Stories that clarified, "On the advice of his doctors and following a diagnosis of an acute upper respiratory infection that has resulted in laryngitis, he is unable to take the stage this evening."

Stewart added to the statement less than an hour before the show was to start.

"Following treatment, I'm feeling much better, but my voice is not."
