After the release of "A Momentary Lapse of Reason" in 1987, Pink Floyd embarked on an 11-week tour to promote the album. The two remaining members of the band, David Gilmour and Nick Mason, along with Richard Wright, had just won a legal battle against Roger Waters and the future of the group was uncertain. Having the success of "The Wall" shows to live up to, the concerts' special effects were more impressive than ever. The initial "promotional tour" was extended, and finally lasted almost two years, ending in 1989 after playing around 200 concerts to about 5.5 million people in total, including 3 dates at Madison Square Garden (5–7 October 1987) and 2 nights at Wembley Stadium (5–6 August 1988). The tour took Pink Floyd to various exotic locations they had never played before such as shows in the forecourt of the Palace of Versailles, Moscow's Olympic Stadium, and Venice, despite fears and protests that the sound would damage the latter city's foundations.
