This 1984 song was Foreigner's biggest hit in the United States AND the UK, the two home countries of the band. Lead singer Lou Gramm hails from the greatest city in America, Rochester, NY. I'm not at all biased.
Gramm's soulful voice is what makes this such a great song. It's clearly a love song - but it's a deeper love song, which goes right to the fear of that initial love - not being sure if you can face the heartache and pain that could happen, but at the same time, love finds the narrator. Backed by the New Jersey Mass Choir, the song gets a larger-than-life feeling that matches the subject matter.
