Rod Stewart may have paused in his lucrative march through the great American songbook, but Garfunkel has picked up the slack with Some Enchanted Evening, his classics-covering 12th solo album. Garfunkel's style is more ethereal than Rockin' Rod's, and his keening version of ''Someone to Watch Over Me'' is genuinely enchanting, as is a nicely swinging ''Let's Fall in Love.'' However, the singer's lifeless reworking of ''I'm Glad There Is a You'' merely proves that the line between delightful mood music and dreary elevator Muzak is a thin one.
