| This was almost left off the album. The beginning of the master tape was kinked and wouldn't play in the tape machine. It was cut out and the ending synthesizer of "Friends" was composited over the edit to disguise it. |
| Not the typical Zeppelin sound, it became more appreciated as it aged. |
| Zeppelin played this on their tours from 1971-1973. A live version appears on their concert documentary The Song Remains the Same. (thanks, Adrian - Wilmington, DE) |
