I knew the day would come when the idea I've had floating around in my head since 2002 would finally be of use. Right around the time when Attack came out and Ben Burtt was doing interviews for the film he was always happy to talk about how he achieved this sound or that sound but for some reason he never wanted to talk about how he did the sonic shockwave sound during the Geonosis asteroid scene. It was always pretty obvious to me and I've wanted to do this or see this done.
Basically, to me those sonic booms have always sounded like the opening to the Boys are Back in Town by Thin Lizzy. Here's the sound effect in the film. I always thought it would be funny to hear the lyric "The boys are back in town" faded in and out after every sonic boom. =P
