I didn't really know any of the tunes from the Rabin era apart from 'Owner', but the handful on the new live album are pretty good in an 80s stadium way.
I've never thought of Steve Howe as scrappy - I think pretty much everything he plays has a point melodically or texturally, and his folk / roots / country influences really shine through to give it warmth. The opposite to, say, Alex Lifeson (speaking as a big Rush fan, btw).
I think Rabin generally does a good spin on SH's parts - I thought he'd throttle them in a flurry of notes, but no.
Incidentally, I just realised last night that poor Rick doesn't get a single writing credit on the new live record / DVD. A bit of an eye-opener, that.
