In 2001, Simon performed on "Son of a Gun" with Janet Jackson on Jackson's album "All for You"; the song was released as a single and peaked at No. 28 on the "Billboard" Hot 100. She also contributed back-up vocals on two songs, "Don't Turn Away" and "East of Eden", for Mindy Jostyn's 2001 album "Blue Stories". In November 2001, Simon's Oscar-winning song "Let the River Run" was used in a public service ad for the United States Postal Service. Entitled "Pride", it was produced to boost public confidence and postal worker morale in the wake of the September 11, 2001, attacks and the 2001 anthrax attacks.
