Steven Tyler performed the National Anthem before yesterday's New England Patriots / Baltimore Ravens game . . . oh my gosh!!!  It was pretty, ummm... peculiar?!  

For the most part, it was exactly what you'd expect out of a Steven Tyler National Anthem . . . only maybe a little worse.  

Most of the haters were ragging on Steven's voice and the fact that he got like 70% of the words right!

One site said he "screeched and murdered" the Anthem, and asked, "How is this guy supposed to pass as a judge on a singing competition when he does this?"  Others wondered if he was sick or had lost his voice.

Meanwhile, the "Boston Herald" defended Steven, sort of.  They called the performance, quote, "pretty decent."

You can find videos on YouTube, but there's also a good quality version on SportsGrid.com.
