Ouch!
Just proves its always better to hear studio “takes” of jingles WITH the music track highly audible “in the mix”! (…noticed lots of sound-bouncing wooden and other bare walls to “reflect & colour” the “raw” sound – bring back cardboard EGG-BOXES for “budget anecoic walling” as anyone in Banff, Macduff or Peterhead 40+ years ago might remember!)
