"Night Flight" was recorded at Headley Grange in 1971 for the fourth album. Besides the usual bass, Jones plays [[Hammond organ]] on the track, and Page plays guitar through a [[Leslie speaker]].{{sfn|Lewis|1990|p=56}} Plant wrote the lyrics after reading a news headline entitled "Nuclear Damage Test Threat" and wondered why there seemed to be little peace and love in the world.{{sfn|Lewis|2010|p=85}}

"The Wanton Song" was built around a Page guitar riff. Unlike some of the other tracks recorded at the 1974 Headley Grange sessions, it was straightforward to arrange, with the group building the song around the riffs.{{sfn|Lewis|1990|p=56}}

"Boogie with Stu" was a jam session with [[Rolling Stones]] pianist [[Ian Stewart (musician)|Ian Stewart]] based around the [[Ritchie Valens]] song "Ooh My Head".{{efn|The track is co-credited to "Mrs. Valens", a reference to Ritchie's mother. The credit came about after the band had heard she never received any royalties from her son's hits.{{sfn|Williamson|2007|p=179}}}} It was recorded in 1971 at Headley Grange during the same session that produced "[[Rock and Roll (Led Zeppelin song)|Rock and Roll]]" for the group's fourth album.{{sfn|Lewis|1990|p=56}} It did not credit Valens or [[Bob Keane]], instead crediting Valens' mother. Eventually a lawsuit was filed by Keane, and half of the award went to Valens' mother, although she was not part of the suit.<ref>{{cite book |last=Lehmer |first=Larry |title=The Day the Music Died: The Last Tour of Buddy Holly, the Big Bopper and Ritchie Valens |publisher=Schirmer |year=2004 |page=166 |isbn=978-0-825-67287-3}}</ref>

"Black Country Woman" was recorded in the garden at Stargroves in 1972 for ''Houses of the Holy'', as part of the group's desire to work in "off the wall" locations outside a traditional studio environment. The track was nearly abandoned when an aeroplane cruised overhead, but it was left on the final recording for effect.{{sfn|Lewis|1990|p=56}}

"Sick Again" was written by Page and Plant about the 1973 tour and their experience with meeting [[groupie]]s. The track was driven by Bonham's drumming and Page's guitar riffs.{{sfn|Lewis|1990|p=56}} The arrangement had been worked out before recording, and was straightforward to put down on tape.{{sfn|Lewis|1990|p=21}}
