John Mellencamp is set to perform at Farm Aid 2026, which will be broadcast live on CNN and feature acts including Willie Nelson, Neil Young, and Dave Matthews. The event coincides with the 30th anniversary of his song 'Mr. Happy Go Lucky,' and he has also announced his Greatest Hits tour, following concert postponements due to wildfires. Mellencamp recently criticized Trump's proposal to rename the Gulf of Mexico during a live performance.
