The geography that helped civilization develop there was because the ground was fertile, it was rich in minerals such a gold, copper, and stone, farmers thrived there, and the capital city, Kerma, was protected from invaders because of the nile cataracts.
This year marks the 40th anniversary of the release of the Led Zeppelin song Stairway to Heaven, which is undoubtedly their magnum opus and biggest hit record of their career. The song was released as a single in January 1972 in the UK, two months after the release of their Led Zeppelin IV album.
But songwriters Jimmy Page and Robert Plant and Warner/Chappell, the song's publisher, pull royalties from record sales, radio plays and live performances. Zeppelin has played Stairway at every performance since 1971, yielding somewhere in the neighborhood of $150,000 in royalties.
