Two-CD/Blu-ray set also features 'Stormbringer' demos, alternate track mixes, song-by-song commentary and more.

"Truthfully, I simply don't want to do anything at this time in my life that will open the door to regret," Whitesnake leader explains.

"It's such a game-changing, life-changing thing," he reflects on his 1973 debut with legendary band.

"It breaks my heart not to do it," says Whitesnake frontman.

Frontman is still committed to the band's farewell tour plans.

Singer David Coverdale is reportedly seeking treatment for a "persistent upper respiratory infection."

Band members have faced various health woes while on their farewell tour.

The Darkness frontman says experience made him “vomit in my mouth – in a really good way.”

It wasn't until guitarist John Sykes added his "embellishments" that Coverdale realized it could be a Whitesnake song.

Singer says he's retiring from the road once this trek is over.
