Vince Gill and Amy Grant

Failed marriages between musicians pepper the history of pop music — even though the morality tales of both Whitney and Bobby and Kurt and Courtney should be enough to convince future generations to keep business and pleasure separate. Of course, hookups in the realm of country music don't always have happy endings (consider Dolly Parton and Porter Wagoner's fruitful but brief affair), but something just feels right about Vince Gill and Amy Grant's marriage. Both singers exude a wholesome charm that matches their soft touch with country music, and their easy-to-swallow voices make the pair ideal duet partners. This show is billed as a Christmas concert, so expect to hear selections from Grant's just-released The Christmas Collection (a retrospective of her three previous holiday collections) and Gill's trio of seasonal discs.
