Both of these artists left us way too soon, but did leave some great music behind. One such example is 1981’s Under Pressure, a song released by David Bowie and Queen.  According to at least one version of the story, David Bowie showed up at Mountain Studios to record backing vocals on the song “Cool Cat” but wound up instead working on ‘Under Pressure’ with Queen. Sources at the time said the band had worked on the song, but was not yet satisfied with. Of course, the rest is rock music history as this monster hit had a profound impact on pop music at the time and beyond, with Stylus magazine saying that it had “one of the best bass lines in pop music history.” Agree?

Below is the a cappella version, and below that is the final released version.
