Narrative:
I was third in a formation at an air show at henry county airport. On landing rollout, with a 15 KT crosswind, the aircraft experienced a spongy left brake and wxcocked to the right approximately 20 degrees. Aircraft left the runway onto the dirt apron. Aircraft came to a stop with no damage to aircraft. On returning to ramp bled brakes and aircraft returned to home base. Probable cause strong crosswind from right on a tail wheel aircraft. Spongy left brake not able to correct for wxcock.
