The New York Post reported that Littrell will be performing at the Times Square Nokia Theater later this month. Sunday's show was postponed.
The Post said that Littrell's performances on tour will consist of him playing acoustic guitar and singing, with no fancy stage props or flashy dance moves. Littrell may also mention some of his trials and triumphs, like being given no chance of living when he was 5, his heart surgery at age 23 and the happiness of his current life as a family man.
"I'm going to talk about how faith and perseverance got me through these things. If Tom Cruise can talk about Scientology, I can talk about Christianity," he says with a laugh.
Littrell, 31, says he aims to take Christian rock and make it popular and non-preachy.
