[Mike the Metal Ed]

A rundown of the cockups today:

Ill Nino take the stage as Turbonegro get stuck in traffic.
Turbonegro play a very good set.
Soulfly take the stage, shortly after we hear that while Slayer there, they are without a crew, and have been moved to the 2nd stage.
Machinehead take Slayer's spot on the festival, while Hatebreed play Machineheads slot.
Luckily, Drowning Pool's set went ahead as planned, and were joined by Soil for a band duet of Halo.
By the time Slipknot take the stage, things seem to have sorted themselves out. The times are running a little late, but smoothly nonetheless.

Until Metallica fail to take the stage.

Finally, at about 9:45-10:00 (with no previous explanation as to the whereabouts of 'tallica), we hear James Hetfield explain that Lars had been taken to the hospital, and they've been looking for a drummer. Slayer's Dave Lombardo took over for the first song (Battery). Then they were joined by still masked Joey Jordison (best choice IMO, he's an awesome drummer and didn't put a stick wrong.)

After a set that comprised of The Four Horsemen, Seek and Destroy, Enter Sandman, Sad But True, Wherever I may Roam, Nothing Else Matters, For Whom the Bell Tolls, and some punk shit, probably off of the later albums.
(Not in that order, I was recalling the songs as I typed them)

THEN, the icing on the cake, we leave for the exit to realise the Showsec rocket scientists decide to close the exit we were leaving by right in front of us. After a standing protest and a shout of "OPEN THESE FUCKING GATES" we were allowed out. (Until roadworks got the better of us leaving Donington)

--EDIT-- I've heard on the Download forums that Creeping Death was played. I honestly don't remember it if it was.
