Singer-songwriter Wayne Mills, who was tragically shot and killed in a Nashville bar last month, is being honored with a concert in his memory. The Wayne Mills Benefit Concert will be held on Wednesday, Dec. 4, and include several of his musical friends.

More than 40 artists have signed up to participate in the event, including Jesse Keith Whitley, Brad Cotter, Tim Scott, Steve Owen and Trent Tomlinson. Members of the Wayne Mills Band will also perform with several of the acts. See a complete line-up here.

The concert will be held at Nashville's Tin Roof, and include an online auction. Admission to the show is free, but donations will be accepted at the door. All proceeds will go to Mills' family, which includes his wife, Carol, and six-year-old son, Jack. The concert will also be streamed live here.

The Wayne Mills Family Fund for Carol and Jack has also been set up at First Bank in Tennessee.

In addition to fronting his own band, Mills also played on the bill with several notable artists, including Blake Shelton, Jamey Johnson and 'American Idol' winner Taylor Hicks.

Chris Ferrell, who shot Mills, claims he fired his gun in self-defense in a fight that happened after he asked Mills not to smoke in the non-smoking section of his bar. A police investigation is ongoing.
