He sang at the afterparty of the inaugural Brett Boyer Foundation Invitational, where earlier in the day at Marshwood Club in Georgia, Wallen participated in a charity golf tournament with fellow country singer Luke Bryan. In addition to his Hot Country Songs chart-topper "Whiskey Glasses" and other hits, the embattled country star also performed the unreleased track "Thought You Should Know," which he teased on Instagram last month. In the song -- which Miranda Lambert revealed in the comments section of his IGTV clip that she and Nicolle Galyon co-wrote -- Wallen updates his mom on his life and questions the "bad decisions" he's made.
The Bright for Brett Foundation organized the charity event, where Bryan's wife Carol serves on the board alongside her brother, Bo Boyer, and his wife Ellen, who respectively serve as vice president and president. The foundation is dedicated to their late daughter and raising awareness about congenital heart disease and Down syndrome.
