Megan Moroney made it through three songs at Ball Arena in Denver on Tuesday night before stopping the show, walking back to the microphone with a hoarse voice and fighting back tears to tell a packed arena that she could not continue. This is like, my worst nightmare. I love you, and I'm really sorry." Ball Arena confirmed the cancellation in a statement: "Megan is unable to continue her performance this evening due to illness, and we must end the show at this time." Moroney, who released her third album Cloud 9 in February, is one of the biggest names in country music right now — she called stopping the show her worst nightmare.
