For better or worse, Yes has veritably lost that child-like innocence that helped them write early gems such as The Yes Album and Fragile.  The four "classic" Yes-men (not including new recruits Igor Khoroshev and Billy Sherwood) are now in their fifties, yet are still playing their hearts out and doing it in style.  It may be a bit shocking to a long-time Yes fan to see the band with so many wrinkles and grey, dyed, or bald heads, but as a relative newbie to the band, I find it very admirable that in their later years, Yes is still a live force to be reckoned with.
