<Tr> <Td_colspan="2"> Problems playing these files? See media help . </Td> </Tr> <P> As in The Dark Side of the Moon, the band used synthesizers such as the EMS VCS 3 (on "Welcome to the Machine"), but softened with Gilmour's acoustic guitar and percussion from Mason . The beginning of "Shine On" contains remnants from a previous but incomplete studio recording by the band known as "Household Objects". Wine glasses had been filled with varying amounts of fluid, and recordings were made of a wet finger circling the edge of each glass . These recordings were multi-tracked into chords, and used in the opening of "Shine On". </P> <P> Jazz violinist Stéphane Grappelli and classical violinist Yehudi Menuhin were performing in another studio in the building, and were invited to record a piece for the new album . Menuhin watched as Grappelli played on the song "Wish You Were Here"; however, the band later decided his contribution was unsuitable and, until 2011, it was believed that the piece had been wiped . It turns out his playing was included on the album, but so low in the final mix that the band presumed it would be insulting to credit him . He was paid £ 300 for his contribution (equivalent to £ 2,300 in 2017). Dick Parry again played saxophone, on "Shine On You Crazy Diamond". The opening bars of "Wish You Were Here" were recorded from Gilmour's car radio, with somebody turning the dial (the classical music heard is the finale of Tchaikovsky's Fourth Symphony). </P> <P> Recording sessions had twice been interrupted by US tours (one in April and the other in June 1975), and the final sessions, which occurred after the band's performance at Knebworth, proved particularly troublesome for Waters . He struggled to record the vocals for "Have a Cigar", requiring several takes to perform an acceptable version . His problems stemmed in part from the stresses placed upon his voice while recording the lead vocals of "Shine On You Crazy Diamond". Gilmour was asked to sing in his place, but declined, and eventually colleague and friend Roy Harper was asked to stand in . Harper was recording his own album in another of Abbey Road's studios, and Gilmour had already performed some guitar licks for him . Waters later regretted the decision, believing he should have performed the song . The Blackberries recorded backing vocals for "Shine On You Crazy Diamond". </P>
