Holy smokes that is awesome. I'm not usually a fan of the rock-band-expands-its-horizons-by-melding-with-a-full-orchestra maneuver. But that was perfect.
And holy smokes, Glenn Hughes killed it.
As a side note, what is the fascination of rock stars calling their audience motherf**kers? I don't get it. Especially in a venue like that, where everyone is pretty much over 40 and paying a hefty ticket price.
