The Yardbirds dissolved in 1968, all band members departing except guitarist Jimmy Page, who constructed a new group consisting of himself, Robert Plant, John Bonham and John Paul Jones to fulfil a contractual agreement to tour Europe, and were allowed by the other Yardbird members to use the name "The New Yardbirds". After the tour, the agreement to use the name expired, and Chris Dreja wrote Page a "cease and desist" notice, so the group chose the name Led Zeppelin, with Grant assuming the role of their manager. His trust in and loyalty to Led Zeppelin was such that his managerial arrangement with the band was via a gentlemen's agreement.
