Even in their hey-day this band never played shows longer than 2 1/4 hours.
You know what's missing from the current show are the medley(s), shortened versions of the songs segueyed together. Always loved the way Queen did that.
Also I always liked the improvs. In the "early" days there was always some improv "jamish" parts in the encore - jailhouse rock/saturday night's alright for fightin etc.
And pyrotechincs...lets not forget the pyros !
