def leppard

These are the first concerts with guitarist Mick Mars' touring replacement.

That was fast.

The song is featured on their latest album, 'Diamond Star Halos.'

Plus: Aerial 'Abbey Road' photography, an Alex Van Halen sighting and ventriloquist REO Speedwagon.

The scheduling gods aligned!

A scheduling coincidence allowed the rock stars to team up for a third time.

Vivian Campbell has stopped members from "killing each other," while Rick Savage is the Spinal Tap "lukewarm water."

Bands powered through injuries and storms on trek's first night.

Things finally calmed down in the second half of their set.

Guitarist Phil Collen says 'Diamond Star Halos' includes "a lot of David Bowie, T. Rex, Mott the Hoople and Queen references."

Death can provide inspiration.

Frontman Tobias Forge says he's not the "Negative Nelly" his lyrics might suggest.
