St Louis: Music icon Lionel Richie has been hospitalised after his concert in St Louis, Missouri, following concerns about his health during the final part of his performance at The Muny on Saturday, August 29.Richie, 77, reportedly checked himself into a local hospital after the show to undergo medical tests.

Richie asked for a chair during final song

Richie performed at The Muny's annual summer-finale concert in St Louis. Towards the end of the show, during his closing number “All Night Long,” he reportedly asked his team to bring him a chair and completed the performance while seated.The incident attracted attention because it followed another health scare involving the singer earlier this year.

Earlier health scare forced concert postponements

In June, Richie fell ill during the opening night of his “Sing a Song All Night Long” tour with Earth, Wind & Fire in St Paul, MinnesotaDuring that performance, he told the audience he was feeling dizzy and “strange” before sitting down during the show. The concert was eventually cut short, and two subsequent performances in Chicago and Columbus were postponed on doctors' advice.Richie later returned to the stage and reassured fans that he was doing well. He also addressed the earlier episode during Saturday's St Louis performance and said he had been told by his doctor that he was suffering from dehydration.
