I heard this today on Underground Garage and naturally assumed it was a modern "retro" act using the name of famous supermodel Twiggy.
Imagine my surprise when the DJ announced that the singer WAS indeed famous supermodel Twiggy - back when she was attempting to launch a singing career in the swinging '60s.
I think if somebody could rescue her vocals from underneath that ridiculous instrumental, we might be on to something.
The song is called "When I Think Of You". I couldn't figure out how to embed it, and sadly there are no YouTubes yet. So check it out at the above link, and let me know what you think.
