It happens to the best of them, as you're about to witness in our newest Loud List. When rock and metal frontmen have played hundreds or even thousands of shows, chances are they've had lyrical mishaps on occasion.

In this Loud List, we've rounded up 10 instances where singers drew a mental blank or got mixed up onstage. These lyric fails were all caught on tape, whether simply caught on a fan's camera or broadcast to millions of people.

Even Iron Maiden legend Bruce Dickinson messes up once in a while. In this case, it was during a surprise duet with Ronnie James Dio for the classic Dio anthem "Rainbow in the Dark." After forgetting the song's lyrics, Bruce owned his mistake, singing, "I don't know all the words to this song, but I know they're never right!" in key with "Rainbow in the Dark."

Some of these blunders were unfortunately immortalized via television, like Staind frontman Aaron Lewis accidentally switching around the National Anthem's lyrics during baseball's 2014 World Series. Senses Fail vocalist Buddy Nielsen also suffered an embarrassing lyrical botch on TV, forgetting the entire first verse to "Rum is for Drinking, Not for Burning" while performing on a 2005 episode of Late Night With Conan O'Brien.
