I have the CD with the complete soundcheck including drum and key check, talking, Puff the magic dragon improvisation, Portobello Belle (!), Romeo and great parts of Speedway at Nazareth. I like the part where Mark asks with a polite voice "What do you want us to play, Robbie?" (from memory, too lazy to have a listen to it now), and as Robbie (Robert Collins I assume) says something like "electric stuff like Speedway", Mark's reply is "coming up..." and they play it, very powerful...
This clip above however seems to come from this CD. So which version was the shorter one you had before?
There is a little bit of talking directly after this clip, and it is a pity that you can hardly understand a thing of it. Mark explains there why he is not happy
with the guitar parts, but I can't understand exactly what he says. He says at some point "...it's not enough for me" and it goes about switching between guitar parts...
