Ludacris Stand Up censored - all lossy?

I'm on my second version of the censored version of Ludacris's #1 hit "Stand Up," and both are lossy. Both the US promo CD single and, surprisingly, the clean version of the "Chicken N Beer" CD album have the song mastered from a 256kb MP3.

Can anyone who owns the censored version of the song on any of the below CDs either do a spectral analysis to see if it's lossless or not, or send me a WAV of the file so I can do the analysis? (A 30-second WAV sample is fine.)

That's what I was thinking... if the sound effects are lossless (and I've already got the full instrumental in lossless), then I could theoretically recreate the clean version (which, by the way, was the stand-alone digital single version, a.k.a. the 45 version).
