Chris Young is less than a month away from releasing his first Christmas album, It Must Be Christmas and in celebration has started a game of "Guess the Guest" on three of the tracks.

The singer uploaded a short 20-second clip of him singing with a familiar voice, urging fans to share their guesses. "Guess The Guest: He’s the first one to sing on this clip," Young writes.

Later, he posted a clip to a completely different song. "Guess The Guest: There are more than II voices on this song," he hints, followed by a third clip on Thursday. "He didn't cut this song on his own Christmas album in 2006," he teases.

Fans were quick to make their bets, deciding that of the special guests is a country icon, another is a popular R&B group and one is an American Idol winner with a voice deeper than Young's: Alan Jackson, Boyz II Men and Brad Paisley!

Young's album, It Must Be Christmas, will be released on Oct. 14, just in time for the holiday season. Young revealed the album's title, artwork and release date earlier this month, but fans are still anticipating a complete track listing and perhaps more guest features.

“This is something I’ve wanted to do for a really long time,” the jolly singer explains in a press release. “Christmas is one of my favorite times of year and it was hard to narrow down the list of songs for this record. I’m excited to share my own versions of many of the standards I sang as a kid every year at Christmas, plus I had the opportunity to write a couple of original songs to celebrate the season."
