Phil Collins scored his second of seven solo Billboard Hot 100 No. 1s, "Sussudio." The meaning of the word? "I set up this drum-machine pad, I got some chords and I started to sing into the microphone, and this word came out," Collins said in 1997. "I went back and tried to find another word and couldn't find one."
Added Collins, "Then I thought, OK, let's give it a meaning, what is it? The lyrics are based on this schoolboy crush on this girl at school. So, 'Sussudio' became a name for this person. My older daughter's got a horse called Sussudio. I'm sure there are children all over the world with the name Sussudio, so I apologize for that."
