Rain Forest by Paul Hardcastle 1984
Paul Hardcastle enjoyed success on the underground dance scene in the early 80s before breaking into the mainstream with "19", an international smash which spent five weeks at number one in the UK.
Personally prefer Rain Forest above 19 every time although both are great tunes.
Can imagine this fitting in nicely with some deep house or slightly more electronic disco these days even 25 years after it's release.
Best get digging and pick up a copy
