Responsible for perhaps more comebacks than any other U.K. Pop artist, Welsh crooner has scored Top Five albums and singles in every decade since his '60s debut chart-topper 'It's Not Unusual.' Is, incredibly, his eighth compilation to chart, only highlighting how extensive his back catalog is. With 29 tracks spread over two discs, it's certainly his most comprehensive hits package, taking in everything from his classic karaoke standards 'What's New Pussycat,' 'Green Green Grass of Home,' and 'Delilah' right up to his most recent career rejuvenation, the critically acclaimed back-to-basics album, from which two tracks, 'Burning Hell' and 'What Good Am I,' appear. Alongside his two number ones and string of Top Ten '60s/'70s singles, the hits package also showcases the reinventions that have prolonged his career far longer than most of his contemporaries. The funky collaboration, 'Kiss,' is a rare example of a cover which doesn't detract from the original, the pulsating 'Stoned in Love' is a successful foray into anthemic dance with producer, while the recent brass-led 'Give a Little Love' is his best entirely solo single since his Las Vegas heyday. But of course the disc is dominated by his most successful recent project, 1999's covers album,, with four of its five singles included here, the best of which is duet 'Burnin' Down the House,' and the remix of 'Sex Bomb.'
