;"You guys like the Beatles?" Metallica frontman James Hetfield asked the audience at a benefit called Acoustic-4-a-Cure. After hearing the crowd's cheers, he deadpanned, "Uh, I've heard of them. This is a beautiful song." Then, in a rare solo appearance featuring the typically fearsome metal frontman armed with nothing but an acoustic guitar, he sang one of the Fab Four's most tender love songs, "In My Life."
