Besides the ending to "Dance..." the other hint would be the "Lamb stew" medley that they did when Bruford toured with them.

There's also no mistaking the difference in the drumming between Bill and Chester with these guys.

It's nice to hear more and more stuff surfacing from this tour.  Maybe someday the powers that be will release all those soundboard tapes from over the years rumored to be boxed away in Phil's closet (or on The Farm) ;-)
