It's hard watching rock stars get old. Billy Joel now makes classical music, Elton John writes for Broadway musicals, and Phil Collins has turned to Disney soundtracks. Meanwhile, at 58, Rod Stewart is warbling standards. After making a commercial comeback with last year's platinum It Had to Be You...The Great American Songbook, Stewart retreads more much-covered classics like "I'm in the Mood for Love" and "Our Love Is Here to Stay" on this equally lame sequel. In fact, most of these tunes simply sound like outtakes from It Had to Be You. Two exceptions are Stewart's duets, with Cher on "Bewitched, Bothered & Bewildered" and Queen Latifah on "As Time Goes By." Cher is not as bad as you might expect, and anyone who saw Chicago knows that Latifah can sing.
