"Grease" is the title song for the 1978 musical motion picture Grease, which was based on the stage play of the same name . It sold over seven million copies worldwide and was featured twice on the film's soundtrack, as the first track and reprised as the final track . </P> <P> Barry Gibb wrote a title song to order for the Robert Stigwood film of the stage musical Grease . The song was recorded separately from, and significantly later than, the rest of the film's songs . Shortly after filming of the 1978 musical film Sgt . Pepper's Lonely Hearts Club Band, Gibb invited castmate Peter Frampton to play guitar on the Grease session . Gibb himself provides backing vocals . The other musicians were some of those from the Andy Gibb album that was being made around the same time . Valli is known for his powerful falsetto voice, but on this track, as with most of his 1970s work, he does not sing in his upper range . </P>

Who sang grease is the word in the movie
