Well, today's the day for the children by the millions (okay, thousands) have been waiting for.
Regarding the live disc, I've read some comments elsewhere by a few who are disappointed that the entire recordings weren't presented in their original order. What I can tell you is that a total of 36 songs were recorded. Four songs were performed three times each. Eight songs were performed twice. Eight songs were performed once. So with the twenty songs on the disc, you're getting the best take of the twelve songs performed more than once and not missing out on any one song. The running order seems to have remained fairly close to the order in which they were originally performed, accounting for the combined performances of course.
Having heard the unedited tapes while doing research for the book, I can tell you that there is a lot of dead space between some songs – often longer than a minute – while the band tunes up, changes instruments etc.. I'm sure you've heard or read by various people associated with Big Star over the years that they didn't have any following to speak of in Memphis. Here you can actually hear it. They finish a song and there's almost NO reaction. Maybe one person randomly applauding. Mostly just conversation and the clinking of glasses and ice. Chilling. Wouldn't we have all loved to have been there and made things different?
I'll be back as soon as my copy arrives – might even be today...
