This is probably the best remnant of what Yes used to be, even without Steve and Chris. Lee Pomeroy does a fantastic job, check out Heart ot Sunrise at about 51:40:

The RRHOF performance had Steve included when they were inducted during that ^ tour, but they were off mostly because of Steve's performance from what I could tell. It seemed his vocals detracted from Jon's and his playing wasn't quite what it used to be. Trevor held a lot of it together.
