Miguel, what a great post! You're going to be quite welcome here, I assure you of that! It is nice to know that someone of your talent and abilities is still having some of the same issues as me.
One of the confounding things about Yes music, for me, with Chris and especially Steve Howe's parts, is one, how they seem to shift somehow, in that, I listen, then work out the part, then when I go back and compare, I don't hear it the same way and my version doesn't always fit. Two, they intentionally seem to play it differently live a lot of the time, especially Steve, not to be clever, but just to keep it interesting. It is a testament to their excellent composing, arranging and recording techniques.
Now, to CTTE. Of course that is what I was tabbing out, the section on the CD from 1:22 to 2:00. I got that riff by taking Steve's riff from 2:01 - 2:08 (between the first and second "ahs")and applying it to the bass, as it sounds to my ear like that is the riff that Chris plays. But, my friend (Pete Greenwood of SEYES, who is probably reading this and laughing) plays it very differently and when he does it, whether his version is right or wrong, it sure seems to work. I even have video of Pete playing that riff on his CS (#1) but at full speed, even that does not help. When I showed Pete how I play that part, he said "What the heck is that?".

So Pete, it's only 24 notes, how about a quick tab for comparison?
If you slow the part down to half speed and don't correct the pitch, you may be amazed to hear that Rick Wakeman is also playing this same riff with one hand at double speed. It's part of what comprises the "musical white noise" in that section of the arrangement.
Yes were simply on fire at this part of their career and the opening of CTTE is their anthem. I was twelve when it came out and it completely blew me away, I wore the grooves off of my first copy. That riff in CTTE and the opening riff of SK (guitar) is what made me start playing. Still gets me, and it doesn't seem to get any easier, although now I can push through a lot of these parts on a good day. Still, I'm 48, these guys were like 22 when they were blazing this stuff out. As Bruford once stated "We were all nineteen and drinking a lot of coffee". What a great time it was to be involved in music.
The "Symphonic" DVD does have a good shot of Chris playing this riff, even longer than the quick shot in Yessongs. I can now play it my way using pick or fingers at album speed and it will work, but Pete's version makes more sense. So, Pete, using the simplified tab style that I used above, what is your take? Anyone else?
Also, from 2:21 - 2:30, Steve slides a basic chord formation up and down the neck of that ES-345, that's another one of those "close but no cigar" parts for me. I use the chord form
A13 D12 G12 B13 (that is a chord, not a riff, in different positions, of course) but Steve uses a slightly different voicing to give it that "growl". I'd like to be able to nail this opening sequence on both guitar and bass, at least good enough to my own standards. I guess I'm saying "Help!"
Also, Miguel, I have both copies of your mp3 for Tempus Fugit and the timing is better on version two for the verse parts. You sure did nail that one! I'd love to hear Yes do it live, Chris could sing the lead part and it would work perfectly!
