The four acts will come together on Nov. 23 at Nashville's Ryman Auditorium for the annual concert, which helps raise funds for the Christmas 4 Kids event that provides more than 400 children each year, from 29 different schools, with a day-long shopping excursion and special party near the holidays. The event has been happening for 25 years.

"This year's show is shaping up to be one of the biggest in years!" says Christmas 4 Kids President Linda O'Connell. "We're so excited to announce the additions of Restless Heart, Shenandoah and Craig Wayne Boyd to this year's show. With the legendary Marshall Tucker Band headlining and this amazing lineup of supporting talent, we're expecting a sell-out crowd!"

This Christmas will be a special one for Boyd for another reason as well: In addition to his recent engagement, the Season 7 The Voice winner and his fiancee, Taylor Borland, are expecting a baby girl in the coming months.

Tickets for the 2015 Christmas 4 Kids concert are available for purchase through the Ryman Auditorium's website and; they cost $36.50 or $60. All proceeds from the concert go directly to Christmas 4 Kids.
