Richard William Wright was the keyboardist and occasionally the lead singer of the Pink Floyd. Wright worked in all the albums of the band except in "The Final Cut "(1983) following the problems with Roger Waters who had excluded him from the group. Wright was re-called by David Gilmour for the finally sessions of "A momentary lapse of reason" (1987) and since that moment he fully returned to be as a official member of the Pink Floyd. Wright had also a solo career and collaborations with Syd Barrett and David Gilmour in their solo albums.
