The performers sang a variety of genres from country to Christian, and seven out of the 12 played guitar as they sang.
Choosing the right song is part of the competition with 10 percent of the final score based on the song's arrangement. Austin Lemaster was one of those who put a lot of thought into his song, performing "Crazy Girl" by the Eli Young Band dressed in cowboy hat and boots.
Some singers joined the contest at the last minute and had less time to get ready for the competition.
"I came the afternoon of the contest, and Bob (Berger) asked me why I wasn't doing the competition this year," said Angela Bennett. "I wasn't sure if I would be back for the final night."
Even though she had only a few hours to prepare, Bennett still made the top six along with Austin Lemaster, Brendon George, Sharon Vore and David Warren.
Judges for the Idol Contest included Adam Verstraete and Phil Greer, who have both judged all three years of the competition, and Amy Sampson, who has judged for the past two years. The top six was chosen for their musical talent, stage presence and arrangement of the song.
This year, the Mocha Jo's Idol contest is being shortened to two nights instead of three. The six finalists will perform two songs of their choice on Saturday, Jan. 28, and the judges will choose the 2012 Mocha Jo's Idol.
"Come on down and enjoy the great local talent in a family friendly atmosphere," said super fan Louetta Burton. "It's the most fun I've had at Mocha Jo's on a Saturday night."
The final round of the contest will begin at 6:30 p.m. on Jan. 28.
