The song was a #13 hit here in the states in late Dec. '84/ Early Jan. 1985.
I "think" it was #1 in Britain but only John F. would know that for sure.
The group featured then popular Brit. acts like Wham!(aka george Michael),Culture Club,Paul Young,Tears For Fears,Duran Duran and many more of the early 80s "new wave" scene.
It was of course the inspriration for Lionel Richie & Michael Jackson to write "We Are The World" by USA for Africa
and "Tears are Not Enough" by Northern Lights w/Gordon Lightfoot.
