Prosecutors found the gun in the Hang on Sloopy singer's carry-on bag on a Delta AirLines flight from Cancun, Mexico.

Derringer told officials he often flies with a gun - and had never experienced any problems.

The guitarist explained he had a pistol permit and thought he could take the gun on airplanes.

He was charged with unlawfully entering an airport's secure area.

His manager, Kenn Moutenot, insists Derringer will work with the government to clear his name.
