Trailer Choir member Crystal Hoyt has left the trio, according to a message posted on the group's website on Tuesday (Feb. 1). The message said she is "departing the group to pursue other interests." The remaining members -- named Butter and Big Vinny -- expressed their support and will continue as a duo. In the message, Hoyt wrote, "We are looking forward to what 2011 has to bring for all of us. Working with Butter and Vinny has been an incredible experience and I wish them nothing but the best." Their singles include "What Would You Say," "Rockin' the Beer Gut," "Rollin' Through the Sunshine" and "Shakin' That Tailgate."
