Country music veteran and 90s star Mark Chesnutt experienced a medical emergency over the weekend, ending up in the hospital and being forced to undergo emergency quadruple bypass heart surgery. In a post on Instagram, Chesnutt wrote "It is with a heavy heart that I announce the cancellation of my upcoming shows. I send my love and gratitude to my family and friends, the band and fans for your understanding, prayers and support, and look forward to seeing you all again soon at a honky tonk near you." For the last several years, Chesnutt has been dealing with a series of health issues, including needing back surgery and an unspecified issue that had him in critical condition last year.
