A Ton Of Country Stars Sing Little Big Town Song Pontoon

It has been the song to sing along with this summer.  Of course I'm talking about Little Big Town's motor boatin' anthem, Pontoon.  A bunch of country artists and celebrities are singing along too, and they come together in this video.

Stars from Darius Rucker to Carrie Underwood, and Luke Bryan make appearances.  Let's play a game.  Who can you spot in the video?
