"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 version recorded on the Heroes tour at the Philadelphia Spectrum, 28-29 April 1978, was released on the live album Stage. To make the song more accessible, it had been lengthened from 2 minutes and 23 seconds to 4 minutes and 24 seconds. 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 the its ending reinstalled.
Another live version can be viewed in the home-video of the "Serious Moonlight" Tour.
