I guess I should know this, but who was the second guitarist (on the the opposite side of the stage from Ollie T and next to the bass player)? I presume his presence had something to do with the heavy/rock sound of the performance.
Overall, it was a powerhouse performance by the band that got me to think of Roxy's 1975 live version of Out of the Blue in which BF's vocals are set atop an incredibly intense and heavy instrumentation (it represents John Wetton at his finest IMHO and Eddie J is certainly pulling his weight not to mention TGPT...).
