Bob Geldof

Ex-member of The Boomtown Rats - an Irish rock band whose biggest claim to fame was the hit "I Don't Like Mondays".
He managed Live Aid and Live 8 action in 1985 and in 2005.
He has been awarded an honorary knighthood, and cannot consequently use the title "Sir". Since The Boomtown Rats ended after their final album "In The Long Grass", Bob launched a solo career. His first album, "Deep In The Heart Of Nowhere" (released in 1986) was probably his most commercial, and it yielded a minor hit with the song "This Is The World Calling".
