The Boomtown Rats were formed by Bob Geldof in 1975 and by 1977 they had their first top 20 hit in the UK "Lookin' After Number One".
Perhaps their most famous hit was "I Don't Like Mondays" which reached number one in the UK and was a massive worldwide hit.
Frontman Bob Geldof also famously organised and recorded "Do They Know It's Christmas?" making millions for Ethiopian famine relief charities. And as if that wasn't enough he then masterminded Live Aid making a further $100 for Ethiopian famine relief.
