"Nancy Boy" is a song by Placebo, released as the third single from their self-titled album. It was released on January 20th, 1997 and it became their breakthrough single, reaching number 4 in the UK charts and making them known to mainstream audiences. As with their first single "Come Home", the single/radio edit (aka the 'Sex mix') is a rerecorded version, noticeably different from the album version. It was later released on the compilation album Once More With Feeling.
The video, shot by Howard Greenhalgh, portrays drummer Steve Hewitt with a blurred face because he was still contractually obligated to another band on a different label. This is also Hewitt's first appearance in a Placebo video after the departure of previous drummer Robert Schultzberg.
