During a recent performance at the Utah First Credit Union Amphitheatre in West Valley City, rock icon Rod Stewart, 81, needed oxygen mid-set to complete his show.

This development comes after a period of canceled and postponed dates for the legendary singer, adding a layer of concern for fans following his "One Last Time Tour."

Audience video captured Stewart leaning against a piano while performing "Young Turks," then steadying himself against a drum screen.

He subsequently turned his back to the crowd as aides brought out an oxygen canister.

The music paused while Stewart took deep breaths, reportedly stumbling backward at one point.

Despite the visible struggle, the crowd offered cheers of support.

After using the oxygen mask, Stewart addressed the audience, stating, "I nearly f*cking fainted up here." He then asked, "Would you mind if I sat down for this one?" and proceeded to settle onto the steps in front of a drum riser.

Reports indicate that Stewart completed the remainder of the concert while seated.

This incident follows a series of scheduling changes for the two-time Rock and Roll Hall of Fame inductee.

Stewart recently rescheduled several performances for his Caesars Palace residency and subsequently canceled four shows while postponing two others.

His current "One Last Time Tour" has been hinted by Sir Rod as potentially his final major tour, a sentiment he echoed at a Hollywood Bowl concert on June 10th, telling the crowd, "This is my last time here, so let’s have a party tonight."
