This is a little post-Led Zeppelin history.
Today in 1983 Robert Plant released his second post-Zeppelin solo album, The Principle of Moments. Led Zeppelin’s Swan Song label had ceased to function by this time, so Plant created his own label, titled Es Paranza, for its release. Billboard hits from the album included “Big Log”, “Other Arms” and “In The Mood”. Genesis drummer Phil Collins played drums for six of the album’s eight songs (as he did in 1982 on Plant’s solo debut Pictures at Eleven), and former Jethro Tull drummer Barriemore Barlow performed on the other two songs.
