Paul Francis Gadd (born 8 May 1944) is an English glam rock singer and songwriter, better known by his stage name Gary Glitter.

Glitter first came to prominence in the glam rock era of the early 1970s. He had one of the longest chart runs of any solo singer in the UK during the 1970s, with a string of chart hits including "Rock and Roll parts 1 & 2", "I Love You Love Me Love", "I'm the Leader of the Gang (I Am)" and "Hello, Hello, I'm Back Again". Between 1972 and 1995 Glitter charted twenty-six hit singles which spent a total of 180 weeks in the UK Top 100. His success as a live performer lasted well beyond the decade. He continued to record in the 1980s and 1990s, with his 1984 song "Another Rock N' Roll Christmas" being one of the Top 30 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 1001 songs in music history."

In 1999, Glitter returned to the public eye when he was sentenced to four months imprisonment and listed as a sex offender in the UK following conviction for downloading thousands of items of child pornography. His reputation was greatly tarnished, and, though he continued releasing new music, Glitter's popularity declined sharply. He moved to Cambodia but was permanently deported from there in 2002 for suspected child sexual abuse, to Vung Tau in Vietnam. In 2005, he was arrested by Vietnamese authorities, was tried and convicted of child sexual abuse charges in June. He was released from prison on 19 August 2008 and returned to London three days later, after being refused entry into Thailand and Hong Kong.
