Brantley Gilbert hobbled up to the microphone on Wednesday night and let fans know that his was the "Gimp Band." In addition to the singer playing with a broken ankle, his guitarist played with an injured knee during a concert in Durham, N.C., benefiting the North Carolina Children's Hospital.

Scotty McCreery, David Nail, Jerrod Niemann and Jason Michael Carroll were the other performers who gave their time for an acoustic night last night. The event was the culmination of a month of charity hosted by Curtis Media Group and WQDR. In total, over $1.1 million was raised to help doctors at the Chapel Hill, N.C. based hospital fight life-threatening illnesses.

Gilbert joked that he hurt himself playing with his godson earlier in the day, but followed that with a quip about that being the story he's telling now. People close to the situation say the 'Country Must Be Country Wide' singer injured himself horsing around with friends last week.

He didn't realize the extent of the injury until after he performed on the bad leg last Friday night. Aside from a noticeable limp and the wooden stool, there was no sign of an injury on Wednesday night. His blue jeans covered up a cast if there was one.

Gilbert and McCreery -- who lives just a few miles down the road in Garner, N.C. -- received the loudest round of applause from the sold out show at the Durham Performing Arts Center. The 'American Idol' winner stuck to songs from his 'Clear as Day' album, finishing with 'Walk in the Country.' He wore a black T-shirt with the words 'Jenna's Warriors' on it, explaining that Jenna was a girl from his hometown who was treated at the Children's Hospital. The audience erupted when he announced that she she was cancer free.
