Along with the album Led Zeppelin also made it into a song.
Although they intended to put the song on the album, the band didn't think that it fit, so it ended up being put on their next album, Physical Graffiti.
Houses of the Holy has amazing songs, such as
The Song Remains The Same
The Rain Song
Over the Hills and Far Away(OTHAFA)
Brad: Do you know what album that song is off of?
Chris: Duh... Houses of the Holy you idiot.
Brad: *sigh* No it's on the album Physical Grafitti. Why don't you go listen to techo or something.
