| Robert Plant dedicated this to his wife, Maureen. |
| This was the first Zeppelin song that Plant wrote all the lyrics for. |
| Jimmy Page played an acoustic guitar solo on this, something he rarely did. |
| This became a showcase for John Paul Jones' keyboard work during live shows. |
| This ends with a church organ that fades to silence and comes back about 10 seconds later. This creates a problem for radio stations, who must decide between accepting the "dead air" or cutting it off. Some stations run edited versions, with the silence eliminated. |
| In 2001, Fred Durst from Limp Bizkit and Was Scantlin from Puddle Of Mudd performed this at the MTV Europe Music Awards. |
| Some radio stations play this together with "The Lemon Song" because there's no pause between them on the album. |
