Singer-songwriters Chris Difford and Glenn Tilbrook have named the new Squeeze album Spot the Difference presumably because there’s so little difference between these versions of their classic power-pop hits and the ones on their sterling 1982 set Singles: 45’s and Under. Frankly, the subtle changes aren’t good. The sharp electric-guitar chops of the original “Another Nail in My Heart” are more muted here. And the only thing that distinguishes the R&B-flavored “Black Coffee in Bed” from its original is the “lite jazz” sensibility in the guitar solo. You can’t really go wrong with such great material, but this cynical ploy to sell an oldies tour is completely superfluous.
