I knew it, I knew it... I sometimes watch Wife Swap with my mom, if I have nothing better to do, or if the families looks like an interesting pairing.. Anyway, I was wondering the same question, but I just knew it had to be Petula Clark... Her voice is very unique (Who can forget "Downtown" and "Colour My World"!) Anyway, I got on last night to google my self to the answer, and it indeed is Petula Clark. The song is "I Couldn't Live Without Your Love"... People used to look at me weird when I told them that I love retro music and collected vinyl records... but this 20 year-old loves the music from yester-year, and it helps sometimes when someone wants to know about a song, eh? Ok, so I signed up only to post this, but I hope that I didn't waste my time to sign up, and you already found out... I hate when I want to know a song and can't find out, so that's why I sign up for this message board...
