Hall of the Mountain King  -  Ritchie Blackmore's Rainbow 

Yep, the one by Edvard Grieg, with lyrics by Candice Night. Several rock and metal bands have their own lyrics and versions of this song. Ritchie would often throw in an instrumental segment during Purple and Rainbow concerts. He said that he first heard it in the early 60's by a British band called Nero and the Gladiators.
