"What in the World" is a song by David Bowie released on his 1977 album Low, later making appearances as repertoire in the 1978 world tour as well as other major tours.
"What in the World" showcases some of Bowie's Berlin-era songwriting and production techniques. The song, like other songs on the Low album, is disjointed, with seemingly random sentences and free-associative phrases appearing throughout the lyrics.
A live performance recorded in the spring of 1978 was released on the album Stage. To make the song more accessible for the concert audience, it had been lengthened by some two minutes. This was achieved by first playing the entirety of the first and second verses at a much slower tempo, practically at dance speed, and then repeating the song once again at album speed with its ending reinstalled.
A live version recorded on 12 September 1983 was released on the concert film Serious Moonlight.
