Waters recreated the "Wall" show in Berlin in 1990, alongside the ruins of the Berlin Wall, and was joined by a number of guest artists (including Bryan Adams, Scorpions, Van Morrison, The Band, Tim Curry, Cyndi Lauper, Sinéad O'Connor, Marianne Faithfull, Joni Mitchell, Ute Lemper and Thomas Dolby). This concert was even bigger than the previous ones, as Waters built a long and high wall. The size of the theatrical features of "The Wall" were increased to cater for a sold-out audience of 200,000 people and of another estimated 500 million, in 35 countries, watching on television. After the concert began, the gates were opened and an estimated 300,000 to 500,000 people were able to watch the concert. This show is available on "The Wall Live in Berlin" album and DVD.
