Niall, do you have an album titled "The First Great Rock Festivals Of The Seventies"? TYA does I Can't Keep From Crying, from the Isle Of Wight. This version clocks in at 19:13. Alvin starts off by saying "Here's a bit culture, a bit of culture" . I haven't seen it yet on YouTube, but I may have missed it. My copy, pops and all, from 1973, has no edits. If you have a copy, great! If not, it's Columbia, C 30807.
Yes Dave I have the track, I had it on vynal years ago, and some kind person from on here put another copy on cassette for me about 10 years back which I transferred to cd. It's the best version of the song I've heard so far, raw & a different pace to the 'Recorded Live' version. I think I did find an upload of the record on youtube( in not good quality) recently.
