Gary Glitter (born Paul Francis Gadd, 8 May 1944) is an English former glam rock singer-songwriter and musician. His long and highly successful career was ended in the late 1990s by repeated revelations of and criminal convictions for possession of child pornography and (in the 2000s) for child sexual abuse.

Glitter first came to prominence in the glam rock era of the early 1970s, with a sustained solo UK chart run and several hits including "Rock and Roll, Parts One and Two", "Do You Wanna Touch Me", "I Love You Love Me Love", "I'm the Leader of the Gang (I Am)" and "Hello, Hello, I'm Back Again". A slight decline in the late 1970s was followed by a successful comeback as a solo artist again from the 1980s. Between 1972 and 1995, Glitter had 26 hit singles which spent a total of 180 weeks in the UK Top 100; twelve of those reached the Top 10, with three charting at number 1. He continued to record in the 1980s and 1990s, with his 1984 song "Another Rock n' Roll Christmas" becoming one of the most played Christmas hits of all time. He released seven studio albums, and at least 15 greatest hits collections or live albums. In 1998, his recording of "Rock and Roll" was listed as one of the top 1,001 songs in music history. The mostly instrumental "Rock and Roll, Part 2" has been played as a popular cheering song at American sporting events for several decades.
