Having made the front pages by defiling America’s most sacred monument, crunching the skulls of winged creatures and, latterly, howling for his pooper-scooper, Ozzy is these days better known for his lack of discretion than his music.

From the jaunty opener “Crazy Train” (“All aboooard!”), through the “Carmina Burana”-marked “Diary Of A Madman” to the more MTV-friendly pop-rock of the ’90s, it’s all here, representing 70 million CDs sold. Let’s, as the man might say, fookin’ rock’n’roll.
