Foster 9, I sense a bit of past tense in your post and I am hoping it relates only to the Yessongs LP! Ha! :-)
Anderson, Howe, Squires, Wakeman, and White have been touring together as YES for the last couple of years and I have been lucky enough to see five of these concerts. At four of the five, they were every bit as good, or better, than they were back in the day. At the fifth, Anderson was not in particularly good voice due to a cold. These guys are still tight, still expertly skilled, and still flat out awesome - if you liked them in the first place, that is. So, if one might hesitate to plunk down the dough for what might be perceived as yet another aging rock band unsuccessfully trying to hang on to old glory - think again! :-)
