Its a good thing ZZ Top wasn't performing. LONDON -- James Hetfield of Metallica may want to re-think the facial hair. The British Broadcasting Corp. reported that Hetfield was detained at London's Luton Airport on Thursday because of his "Taliban-like beard." He was not allowed to leave the terminal but was released after questioning. Metallica performed at the London Live Earth concert on Saturday. Metallica is currently touring in the United Kingdom for their Sick of the Studio summer tour.
