After the departure of Keith Relf and Jim McCarty in 1968 , Page reconfigured the group with a new line-up to fulfil unfinished tour dates in Scandinavia . To this end , Page recruited vocalist Robert Plant and drummer John Bonham , and he was also contacted by John Paul Jones , who asked to join . During the Scandinavian tour , the new group appeared as the New Yardbirds , but soon recalled the old joke by Keith Moon and John Entwistle . Page stuck with that name to use for his new band . Peter Grant changed it to " Led Zeppelin " , to avoid a mispronunciation as '' " Leed Zeppelin . " '' Led Zeppelin are one of the best-selling music groups in the history of audio recording . Various sources estimate the group 's worldwide sales at more than 200 or even 300 million albums . With 111.5 million RIAA-certified units , they are the second-best-selling band in the United States . Each of their nine studio albums reached the top 10 of the US Billboard album chart , and six reached the number-one spot
