Mary Isobel Catherine Bernadette O'Brien OBE, professionally known as Dusty Springfield, was an English pop singer and record producer whose career extended from the late 1950s to the 1990s.

At her peak, she was one of the most successful female recording artists, with six top 20 singles on the US Billboard Hot 100 and 16 on the UK Singles Chart from 1963 to 1989. She is a member of the Rock and Roll Hall of Fame and the UK Music Hall of Fame.

Her solo career began in 1963 with the upbeat pop hit, "I Only Want to Be With You". Among the hits that followed were "Wishin' and Hopin' " (1964), "I Just Don't Know What to Do with Myself" (1964), "You Don't Have to Say You Love Me" (1966), and "Son of a Preacher Man" (1968).

As a fan of US soul music, she brought many little-known soul singers to the attention of a wider UK audience by hosting the first national TV performance of many top-selling Motown artists beginning in 1965.

In a 1970 interview with Roy Connolly of the Evening Standard, she addressed the rumors about her sexuality.

Many other people say I'm bent, and I've heard it so many times that I've almost learned to accept it... I know I'm perfectly as capable of being swayed by a girl as by a boy. More and more people feel that way and I don't see why I shouldn't.

She later moved to the US, where she experienced a career slump for several years. However, in collaboration with Pet Shop Boys, she returned to the Top 10 of the UK and US charts in 1987 with "What Have I Done to Deserve This?" In the mid-1990s, owing to the inclusion of "Son of a Preacher Man" on the Pulp Fiction (1994) soundtrack, interest in her early output was revived. Springfield’s music has appeared in 177 films or television shows. Her 1979 cover of "Spooky" was also heavily featured in Guy Ritchie's Lock, Stock, and Two Smoking Barrels (1998) and has since become a favorite of many Halloween playlists.
