Charlie Puth & Life Of Dillon were scheduled to open for Meghan Trainor at the fair August 22nd, but Meghan had to cancel the remainder of her tour due to vocal cord surgery.

Instead of scrambling to find a last-minute replacement, Iowa State Fair organizers decided to have the two opening acts headline the Saturday night Grandstand show.

Tickets cost nothing: The show will be free to help placate disgruntled fans. Gates open at 7 p.m., and the concert begins at 8. Seating will be general admission. [Des Moines Register]
