Jimmie Allen was excited to perform with the Zac Brown Band and Marcus King on the CMA Awards last night… then got sick. Hours before the show, Allen tweeted "I was looking forward to performing with my friends @zacbrownband and @realmarcusking at the @CountryMusic Awards, unfortunately I'm under the weather and won't be able to. I look forward to watching them and the other performers tonight." The artists were set to perform the Zac Brown Band song "Out in the Middle.”
