The stage performances of '' The Wall '' ended with " Outside the Wall " after " The Trial " , where the performers came walking over the stage in front of the now demolished wall , playing acoustic instruments and singing the vocal tracks . Waters played clarinet , and recited the lyrics , while the backing singers sang the lyrics in harmony . David Gilmour played mandolin , Richard Wright played accordion , Willie Wilson played tambourine , Andy Bown played 12-string acoustic guitar , and Snowy White ( replaced by Andy Roberts for the 1981 shows ) , Peter Wood and ( unusually ) Nick Mason played 6-string acoustic guitars . A similar format was used for the track during Waters ' 2010-2013 tour , '' The Wall Live '' , including the appearance of Gilmour playing the mandolin and Mason playing a tambourine
