Cher coughs up a good show

Like it or not, pop music dominated the charts and radio waves last year. Much was as sweetly maudlin as sugar cane, but there were some enjoyable and ultra-fun mainstream grooves. Two of the most successful ditties were definitely freshman Lou Bega's "Mambo #5" and, in one of the most phenomenal comebacks, Cher's "Believe." So the pairing of the two on a tour, which stopped at the Fleet Center on Friday, March 3, made more good economic sense.
