Something else may have happened.

We all know how the lyrics of most rock songs are buried under the guitars. This means the censor has to listen for changes from published lyrics.

It may be that the censor, listening for lewd content, detected lyrics that didn't match the
expected lyrics, but was unable to understand the lyrics he heard in time to make a decision without error. Since there is a fine for letting lewd lyrics through, he may have erred on the side of safety for the firm and pushed the button.

I can imagine several lewd phrases the censor could have heard instead of "George Bush" when it is buried under guitar.
