Hi MuzikTyme, hmmm...I think we need to forget about it being any rendition of 'How am I suppose to live without you' as I have double checked the lyrics to that song, and they are not the same at all, apart from 'how am I suppose to live' including 'my life' before 'without you' which I guess is just a coincidence, but thank you for your suggestion
I think 'Now that you no longer want me (or need me) are more likely candidates to appear in the song title somewhere, as it is in the chorus.
But it could be one of those songs that has a title that doesn't even get mentioned in the lyrics, plus it may only really be known around Europe, and don't think it reached the States, but who knows?
Music goes like: (Piano) 'dum dum dun' Bass follows 'ba dump a dump' repeat a couple of times, then the piano goes up a key or so, then the comes in.
Maybe that info is useless, as I'm no musician, but it could jog someones memory hopefully. But I can see this is gonna be a difficult one to fathom out!
