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 125,000. During this gig Clare Torry sang backing vocals making it the second and last time she did so. Vicki and Sam Brown also attended as backing vocalists, as well as Candy Dulfer with saxophone solo. The £60,000 firework display that ended the concert was entirely financed by the band.
