BY Daniel DurchholzRock's most sure-handed journeyman, Paul Carrack is slowly working his way around to singing with every band in existence. And why not? He's had success with more than a few already, scoring hits with Ace (How Long), Squeeze (Tempted), Mike & the Mechanics (Silent Running (On Dangerous Ground)), and as a duet partner with Carlene Carter (Do Me Lover). The Paul Carrack Collection combines those tracks (plus some others) with the cream of Carrack's solo work, including the hit I Need You. Carrack is perhaps the most-heard, least-known vocalist in rock, though this set goes a long way toward righting that wrong.
