Robert Frederick Zenon Geldof is an Irish singer-songwriter and political activist. He rose to prominence in the late 1970s as the lead singer of the Irish rock band the Boomtown Rats, who achieved popularity as part of the punk rock movement. The band had UK number one hits with his co-compositions "Rat Trap" and "I Don't Like Mondays". Geldof starred as Pink in Pink Floyd's 1982 film Pink Floyd – The Wall. As a fundraiser, Geldof organised the charity supergroup Band Aid and the concerts Live Aid and Live 8, and co-wrote "Do They Know It's Christmas?", one of the best-selling singles to date.

The Boomtown Rats are an Irish new wave band originally formed in Dublin in 1975. Between 1977 and 1985, they had a series of Irish and UK hits including "Like Clockwork", "Rat Trap", "I Don't Like Mondays" and "Banana Republic". The original line-up comprised six musicians; five from Dún Laoghaire in County Dublin; Gerry Cott, Simon Crowe (drums), Johnnie Fingers (keyboards), Bob Geldof (vocals) and Garry Roberts, plus Fingers' cousin Pete Briquette (bass). The Boomtown Rats broke up in 1986, but reformed in 2013, without Fingers or Cott. Garry Roberts died in 2022. The band's fame and notability have been overshadowed by the charity work of frontman Bob Geldof, a former journalist with the New Musical Express.
