Every two years, Bill Gaither and his friends come to town. They sing for the nice and naughty, and everyone gets the same gifts of country gospel and celebration. Gaither's holiday concerts, which are called "homecomings," have grown from an informal gathering of musicians in Nashville to a touring juggernaut, topping industry lists for most concert tickets sold worldwide. On Gaither's list this year is the Gaither Vocal Band, Ernie Haase & Signature Sound, Jeff & Sheri Easter, Lynda Randle, Ivan Parker, The Isaacs and others. Gaither and the gang perform Friday, Dec. 14, at 7 p.m. at Richmond Coliseum. $20.50-$37.50. Call 262-8100 or visit www.ticketmaster.com.
