"Arthur's Theme (Best That You Can Do)" is a song performed and co-written by American singer-songwriter Christopher Cross, which was the main theme for the 1981 film Arthur starring Dudley Moore and Liza Minnelli. The song won the Oscar for Best Original Song in 1981.[1] In the US, it reached number one on the Billboard Hot 100 and on the Hot Adult Contemporary charts during October 1981, remaining at the top on the Hot 100 for three consecutive weeks. Overseas, it also went to number one on the VG-lista chart in Norway and was a top-ten hit in several other countries. The song became the second and last American number-one hit by Christopher Cross.[2] It was included as a bonus track only on the CD and cassette versions of his second album, Another Page, released in 1983. The B-side of the record, "Minstrel Gigolo", was the same song used on the back of Cross's debut single, "Ride Like the Wind". Indie pop band Fitz and the Tantrums recorded a cover of this song for the soundtrack to the 2011 remake of the film.
