Rock icon LEMMY KILMISTER made a shock appearance at a Metallica concert in the U.S. on Monday night (14Sep09) when he joined the band onstage.
The Motorhead frontman appeared during Metallica's encore at Nashville, Tennessee's Sommet Center, and performed his hits Damage Case and Too Late Too Late alongside the James Hetfield-fronted band.
The two groups haven't always been close - Motorhead once released a mocking cover of Metallica's Enter Sandman, called Enter Sandman (F**k Metallica).
