Petula Clark, (born November 15, 1932), is an English singer, actress and composer, best known for her upbeat popular international hits of the 1960s. Remember "Downtoown, things will be great when you're dooowntooown"? Sure you do. Yep that's her. She lived in France for some years, before she got her global breakthrough. I'm really not into her English stuff, but the French - wowzie it's great!
Petula wrote this song as a James Bond theme, apparently disappointed that she wasn't given the chance to do such a theme. It's no secret that I love James Bond music, but this song just isn't for Bond - it's too uptempo and fun - but still love it though! (I have no idea what the male puke sounds is about, maybe it's suppose to sound like a fight?)
Update: Thanks to Le Chpoum, we now have the English translation of the song. Go to the comments and try to follow the lyrics while playing the song. I did that, and I like it even more now!
