Does anyone know why, though, that it wasn't bothered with for ITTOD? It seems very complete, at least, musically speaking (lyrically might have needed some work), and was much more in spirit with Zep's 'sound', but more mature--it'd have fit on ITTOD more than some of the other songs. I mean, why it never turned up even on say, Coda, is beyond me.
The ending of the demo suggests, though, Page wanted it to be longer--like it fades to what Page might have envisioned as a slow breakdown part.
I just hear another classic, epic in the making in this song.
