I have no doubt in my mind concerning two things:
1. Raff's version of the song wouldn't stand the same chances to become a hit,
if it wasn't for late Laura Branigan's cover version &
2. Laura's version may not be italo disco, but it is clearly superior compered
to Raff's version.
The two song versions were on the top of the German charts on July the 5th, 1984
(#1 for Laura & #2 for Raff).
Laura had also a huge hit in my native Hellas with Tozzi's Ti amo,
not to mention other covers such as Forever young (Alphaville).
Is it a coincidence that the biggest hit for both Raff (or Raf as he is known today)
& Umberto Tozzi in Hellas is their duet Gente di mare (1987)?
Life moves in mysterious ways!
