Rod Stewart turns to oxygen tank mid-concert after nearly collapsing onstage

Rod Stewart nearly suffered a medical emergency mid-show just weeks after canceling multiple gigs over health issues.

On Friday, the 81-year-old musician — who was performing at the Utah First Credit Union Amphitheatre in West Valley City — sparked concern after noticeably slowing down mid-concert.

In a video obtained by TMZ, Stewart began to heavily lean on various pieces of equipment while still attempting to perform. At one point, he turned around and gave a nod to a team of people backstage who quickly tended to him.
