Ha ha, I seem to have solved the mystery!! I thought I was going mad but after your last reply I thought well I can't hear it Then it struck me. I am deaf in one ear so I turned my headphones around and voila the French lyrics sung by the girl could be heard so I obviously have problems with some versions in stereo because the girls singing only is heard through my right headphone!! Same goes with that version on the TV.
I probably have been listening to different versions of songs to the rest of the population for the last 40 odd years!!
Sorry David, thanks for helping me solve it. I'll now go away and listen to my entire back catalogue of Ultravox with my headphones on back to front and see what I have been missing for decades!!
What a plonker I am!!!
