Jon Lords (keyboards) starts the song with an emotional vocal delivery David Coverdale. The song starts off slow  until the guitars and drums merge in then the  tempo drastically changes and becomes a hard driving rock song. The ballad section of the song doesn't kick in again until the middle and end of the song.

The video depicts the band performing the song at a mock concert, with David Coverdale running after an unknown woman.
