Question: Was the friend who the song was a "sugar-coated" farewell to born before 1980? Passage:According to the sheet music published at Musicnotes.com by BMG Rights Management, "Goodbye" is set in common time with a key of E major. The girls' vocals range between G to C. The song has a slow tempo of 68 beats per minute. The song is a ballad which has the girls singing what Sarah Davis at Dotmusic called a "sugar-coated" farewell to friend Geri Halliwell, who left the group months prior. Coming to a similar conclusion, Kristie Rohwedder (with Bustle) noted that in the chorus of the song, the Spice Girls sing "Goodbye my friend/I know you're gone, you said you're gone, but I can still feel you here" and "It's not the end/You gotta keep it strong before the pain turns into fear".
