[Kraftwerk] Concert Classics / Tribal Gathering - info wanted

I recently purchased a copy of the Concert Classics CD which was discussed on this list a few years ago when it was released and was wondering if one of the knowledgeable list members could tell me: a) When and Where this was recoded b) What the proper titles of the 'Morgenspaziergang' tracks are Also, I rediscovered the cassette recording that I made of the BBC Radio 1 broadcast of Tribal Gathering in 1997. I seem to remember that some of the tracks were broadcast at the wrong speed - again can anybody tell me: a) Which tracks are at the wrong speed b) What correction needs to be made for them to run at the right speed Regards Simon
