It's never easy to cover a rock song that's had extreme influence on modern music, but Panic! At The Disco did a great job of it with their cover of The Darkness' "I Believe In a Thing Called Love." Watch as they nail every electrifying guitar solo, every pounding drum section, and most impressive of all, every mind-blowing high note. After this performance, it's safe to say nobody can question Panic!'s ability to tackle classics-- or frontman Spencer Smith's Brendon Urie's ability to wail out notes so high they shouldn't even exist.
