Greg Lake took on the management of the ELP. He stated in an interview in 2003 that the three were not good friends. They were very much a working partnership. He had been producing King Crimson’s records and took on the same role with ELP. But the band got so popular so fast that Lake realized he could not wear all the hats anymore. They needed management and quickly. They were just about to sign on with Peter Grant who was successful with Led Zeppelin… but Jimi Page stepped in.
