Initially, there was a great deal of uncertainty around the tour. Pink Floyd had not played live since 1981, and had not embarked on a full-fledged tour since 1977. Roger Waters left the band in 1985, believing the band would not continue. However, Gilmour and Mason decided to continue as Pink Floyd. Waters threatened legal action against Gilmour and Mason, as well as any promoters who promoted shows as "Pink Floyd". However, by the end of 1987, with the success of the album and first stages of the tour, the new lineup had established itself commercially, and the band reached a settlement with Waters in December. 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 197 concerts 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. A further concert was held at the
Knebworth Festival in 1990, a charity event that also featured other Silver Clef Award winners. Pink Floyd was the last act to play, to an audience of 120,000. During this gig
Clare Torry joined
Vicki and
Sam Brown in providing backing vocals,
Candy Dulfer contributing saxophone solos. The £60,000 firework display that ended the concert was entirely financed by the band. These shows are documented by the
Delicate Sound of Thunder album,
video and ''Live at
Knebworth '90'' video. Video of both the Venice and Knebworth concerts was released on
Blu-Ray and
DVD in
The Later Years boxset. ==Personnel==
