>> My collection from the 78 & 81 tours doesn't have any SFTD <<
right - i believe the history (so far) of SFTD in concert goes like this: 68, 69, 70, 75, 76, 89, 90, 94, 95, 97, 98, 99, 02, 03, 05.
now i feel like spending a while comparing SFTDs, but off the top of my head i remember the 68 rendition as closest to the studio version,
but i'm very likely wrong - comparing concert renditions with studio versions isn't really something my own personal mind naturally leans toward.
(someone recently asked why JJF isn't played in concert the way it is in the studio, and my main reaction was just: "because the stage is totally different from the studio."
which sure is true, not to mention the personnel changes and other developments over 37 years - but still, i'm sure there are more insightful things to say about it.)
