[The Song Remains The Same - upcoming screening]

The film format used for the concerts had inherent limitations. I've got some specific details written down somewhere. I want to say the cannisters had to be swapped out

every 20 mins or so.

that makes sense

plus they didn't have a large number of cameras at the time

so there were holes in the video that needed to be filled in

the shepperton sessions of course happened because not enough planning went into the the filming of the ending three shows of the 1973 tour

if youlook closely at some of the shots of TSRTS you can see different hair lengths and Plant had work done on his teeth

theres probably more too

how much time went into the Shepperton sessions?

[Final U.K. Date December 10, 1975]

i think that if you look at the photos in the booklet for the early and latter days you'd find a photo in there from that

give it a look
