"Custard Pie" was recorded at Headley Grange in early 1974. The first take was played at a faster tempo than the finished version, with various improvised vocals. After a basic run-through, the group then discussed possibilities for rearranging it.{{sfn|Lewis|1990|p=21}} Page played the guitar solo through an ARP synthesiser, while Jones overdubbed a [[Hohner Clavinet]] part and Plant played harmonica.{{sfn|Lewis|1990|p=55}}

"[[The Rover (Led Zeppelin song)|The Rover]]" was written in 1970 at [[Bron-Yr-Aur]], a cottage near [[Machynlleth]], [[Wales]]. It was first recorded at Headley Grange in May 1970 as an acoustic number for ''[[Led Zeppelin III]]''. It was reworked as an electric number in 1972 for ''[[Houses of the Holy]]'', which formed the basis for the backing track.{{sfn|Lewis|1990|p=19}} Page subsequently added guitar overdubs in 1974 with Keith Harwood engineering.{{sfn|Lewis|1990|p=55}}{{efn|The original sleeve features the credit "Guitar lost by Nevison, salvaged by the grace of Harwood" and refers to the various recording sessions for the track.{{sfn|Lewis|1990|p=55}}}}

"[[In My Time of Dying#Led Zeppelin version|In My Time of Dying]]" is based on a traditional song that [[Bob Dylan]] recorded on his [[Bob Dylan (album)|debut album]] in 1962.{{sfn|Lewis|1990|p=55}} The track was recorded live, with Page later adding further [[slide guitar]] overdubs. The arranging and structuring was led by Bonham, who worked out where the various stop / start sections in the track should be, and how the group would know where to come back in. The very end of the song features his off-mic cough, causing the rest of the group to break down at that point. Bonham subsequently shouted "That's got to be the one, hasn't it?", feeling it was the best take.{{sfn|Lewis|1990|p=22,55}} It was left on the album to show fans that Led Zeppelin were a working band that took care in their recordings.{{sfn|Williamson|2007|p=234}}
