Toto, "Africa" (1983)
As a collection of top-notch studio pros, Toto didn't put the singer front and center, but Bobby Kimball and Steve Lukather usually handled the vocals. On their only Number One single, however, cowriter David Paich took the microphone. He said the song threw the group for a loop: "Bobby tried it, then Lukather tried it, but it had what I call an 'Elton John mouthful' of words: lots of words to get in, in a very short amount of time. So I ended up singing it because I could spit out these words fast enough."
