These guys were my first, and one of the most memorable, concert. My Dad sat through it with me and my girlfriend and when John Deacon was a little late getting to the stage for their acoustic set Freddie Mercury says "He's probably out back getting a blow job." Talk about embarrassing...

From YouTube:

David Bowie & Queen ~ Under Pressure. A collaboration with David Bowie, this is credited to "Queen with David Bowie" because the B-side of the single is Queen's "Soul Brother." It was recorded at an impromptu session in Montreaux, Switzerland.
According to Queen bass player John Deacon, Freddie Mercury did most of the songwriting on this, although everyone contributed. The lyrics deal with how pressure can destroy lives, but love can be the answer. The lyrics are characteristic of Mercury's songwriting.
In the US, this was on Queen's Greatest Hits album and released as a single at the same time. It was not released on a UK album until 6 months later, when it was included on Hot Space.
