Wishes Fireworks Show

[KINGBOBOFTHENORTH]

I was watching the Wishes fireworks show last night from a parking lot. People in a car nearby were doing the same, and they had the audio playing from their car speakers. Do any of you know if the audio is broadcast on the radio in Orlando (i.e. Disney Radio) or were they probably playing a CD that has the Wishes soundtrack? Do they sell that at DTD?

Thanks,
