You just have to find a way to incorporate the radio stations and taxi radios into the performance. I saw Frank Zappa and the Mothers of Invention on an afternoon bill with Miles Davis in the headlining slot at the 1969 Newport Jazz Festival. The 69 festival had the biggest crowds to date due to the inclusion of a few rock bands so there were 40,000 people at, or in the vicinity of, the festival. Frank had written music especially for the festival and had a CB radio tuned to the police channel (which was getting a ton of activity due to the huge crowds) and patched into the PA so random bursts of police communications would come blaring out of the PA while they were playing. Great show.
Wow, that is a night to remember, indeed!
