Close to the Edge and The Gates of Delirium - Studio Run-throughs

In the last years, many re-releases of Yes albums have featured as bonus tracks studio run-throughs, former versions of the songs that would still be modified before being released. Today I'll put here two studio run-throughs, of Close to the Edge and The Gates of Delirium.
Close to the Edge is generally the same, but there are many missing points. Since the beginning, for the first introduction, with the sounds of nature and birds, is inexistant! later, there are a few changes in lyrics and instrumentation, but the song is mostly the one we're accustomed with.
The version of The Gates of Delirium is much more distant from the final arrangement. Jon was still writing the lyrics, so he sung some "la-na-nas" and there's an amusing part where he improvises: "instant call that soils the sandwich (...) and we fight all to the devil, in regardness of the cats". If some critics say Jon often has no idea what he's singing about, I imagine what they'll say of that!
The song is overall very different, with louder drums(!) and less keyboards. The last part, Soon, is absolutely another one, with drums, electric rhythm guitar and almost no steel guitar. It lacks the calm and beauty of the one we know so well.
Listening these two studio run-throughs is very interesting, first to give us an idea of the band's process of composition, and also to remind us how both songs were so well and carefully produced, and sometimes a slight detail missing can spoil its greatness.
