At a rock concert a man dressed in black and white pants and a checked hat plays his red guitar while another man sings.
Aerosmith is in town but only two members are sober enough to perform, and one wears a hat.
Any band could have a member dressed in a hat, and being dressed a certain way does not mean a person lacks sobriety.
