It states: "Below is a list of band names that cannot be said in any way over the air. They cannot be used in any stories by newscasters or in bewtween [sic] songs of DJ's. If you say any of these bands, or play any of their music, YOU WILL BE SUSPENDED! Please use your best judgement and always consult a manager or Mr. M--------- if you have any questions. Anything with Devil, Satan, God, Jesus, or any other catholic references that are portrayed in a negative light should not be discusssed [sic] over air. But here is a list for your own personal enjoyment."
Although it looks legit, I have no way of verifying it. But, have a look for yourself!

I had to chuckle at the list, and besides, who plays most of these bands on mainstream radio anyway?
People who played Anal C–t called them AC on the air. Not on the list is the Butthole Surfers; in a review of their concert, the Boston Globe called them the BH Surfers (thought butthole was safe enough to say tho).
Did you notice the list at the bottom that is cause for TERMINATION? That might be a clue as to the seriousness of this “memo”.
