The collaboration between Queen and David Bowie resulted in one of the most iconic basslines in history. The session took place in Montreux, Switzerland, during a marathon 24-hour period fueled by wine and improvisation. The famous bassline was created by Queen's John Deacon, but according to Brian May, Deacon actually forgot the riff after the band went out for pizza; Roger Taylor had to remind him how it went. Bowie insisted on a 'scat' vocal style for the verses, which gives the song its spontaneous, urgent feel. The song became a number-one hit in the UK and a Top 30 hit in the US. Years later, the bassline became the center of a legal dispute when it was sampled by Vanilla Ice for his hit 'Ice Ice Baby.' Vanilla Ice famously (and unsuccessfully) argued that the two riffs were different because he added an extra 'beat' between the notes.
