Yeah, I sat across from Stanley the entire time that he was doing the voice of DeCazador. I can pick the difference, but that's me.
There's a blooper somewhere that I saved (I'm planning to put together a BMI blooper reel) that has me trying to sort out the LeChuck voice. And yeah, I had trouble not straying too much into 'Vapour' territory. Which, incidently, is me doing a dodgy impersonation of John Goodman.
And don't worry, I'm not taking it the wrong way. It's a problem I'm aware of, and something I keep in mind every time I approach a new radio idea - what voice can I do that sounds different enough from previous radio series.
