It's unclear whether Hank Williams Jr. voluntarily permanently removed himself and his music from ESPN's Monday Night Football or whether ESPN permanently fired him, but this much became clear on Thursday -- you won't be hearing Williams's voice at the beginning of the NFL telecast ever again. Williams on Thursday appeared to take back the apology he had issued on Wednesday after saying that he had received thousands of messages from supporters urging him not to back down from his earlier comments in which he compared President Obama to Hitler. One of his supporters turned out to be Rush Limbaugh, who himself had been similarly axed by ESPN for comments he had made during a Monday Night Football telecast in 2003 that were deemed racist by the cable sports network. (And as recently as 2007 he remarked on his radio show, "The NFL all too often looks like a game between the Bloods and the Crips without any weapons.") "It's official now," said Limbaugh on his syndicated radio show Thursday. "All public references to Adolf Hitler are banned unless you compare Hitler to Republicans or Tea Party supporters. You can do that, but if you compare Hitler to Democrats, you are finished." The Hank Williams song became The Anthem for Glenn Beck's radio show on Thursday. "ABC [sic] can be a wuss, but we aren't. Turn the song up!" he commanded. "Enough is enough," Beck remarked later. "I know nobody's gonna give up MNF, but I am."
