<Tr> <Td> Che! (1969) Che! 1969 </Td> <Td> Kelly's Heroes (1970) </Td> <Td> Rock Requiem (1971) Rock Requiem 1971 </Td> </Tr> <P> The film score was composed, arranged and conducted by Lalo Schifrin and the soundtrack album was released on the MGM label in 1970 . </P> <P> The soundtrack was released on LP, as well a subsequent CD featuring the LP tracks, by Chapter III Records . This album was mostly re-recordings . An expanded edition of the soundtrack was released by Film Score Monthly in 2005 . The main musical theme of the movie (at both beginning and end) is "Burning Bridges," sung by the Mike Curb Congregation with music by Schifrin . There is also a casual rendition of the music in the background near the middle of the film . The Mike Curb Congregation's recording of "Burning Bridges" reached number 34 on the Billboard Hot 100 singles chart on March 6, 1971, but did much better on the charts in Australia, where it spent two weeks at No. 1 in May that year . In Canada, the song reached number 23 in March 1971 . </P> <P> The soundtrack to the film also contains the song, "All for the Love of Sunshine," which became the first No. 1 country hit for Hank Williams, Jr...The inclusion of the song in the film is an anachronism, because the song was not released until 1970, twenty - five years after the end of the war . </P>
