Bill Murray appears as a '70s rocker at a guitar festival in 2007. Murray will appear in the Chicago Air and Water Show in August.

Former "Saturday Night Live" cast member Bill Murray has agreed to parachute from a plane as part of a special appearance at the Chicago Air and Water Show next month.

A spokeswoman for the Mayor's Office of Special Events says the 57-year-old actor is jumping on behalf of USO of Illinois.

The Chicago native will tandem jump with the Golden Knights skydiving team onto North Avenue Beach on Aug. 15th.

It is the 50th anniversary of the popular show on Chicago's lakefront.
