Many of the biggest names in country music – including Luke Bryan, Darius Rucker, Sara Evans and the ladies of Pistol Annies – have come together in a hilarious viral video for Little Big Town’s summer smash anthem, “Pontoon.” In the clip, a slew of country artists can be seen belting out the tune in different scenes, some laughing too hard to keep a straight face. Eli Young Band, Lady Antebellum, Wynonna Judd, Jake Owen and Hunter Hayes also make appearances. “Pontoon” has garnered nearly four million views on YouTube in its original form, and is quickly approaching platinum status on Billboard’s Digital Songs chart. The track is Little Big Town’s fastest-rising single to date, vaulting to No. 3 on the country charts in just 16 weeks. “Pontoon” is the first single from “Tornado,” which comes out September 11th.
