Roberts’s father, Rex Roberts, played double bass with a dance band called The Melodists in the 1940s. The headmaster at The High School, Dublin, calls his father in one day to suggest that he consider move his son to a boarding school as he is spending a lot of time in detention.
After being bribed with the promise of a bicycle, Roberts is moved to a Quaker-run boarding school, Newtown School, Waterford. The move proves successful but not for the anticipated reasons. He quickly takes notice of the electric guitars of the school band and realizes that is to be his future.
In 1976, Roberts and Johnnie Fingers (Moylett) decide to put a band together and, between them, they recruit the other four members, Pete Briquette (bass), Gerry Cott (guitar), Simon Crowe (drums) and singer Bob Geldof to form The Boomtown Rats.
Following the breakup of The Boomtown Rats in 1986, Roberts works with Simply Red, Orchestral Manoeuvres in the Dark and Flesh For Lulu in the role of audio engineer on tours in the UK and the United States. He avoids playing the guitar in public for ten years, after which he and Simon Crowe play together for four years in the rhythm and blues four-piece band The Velcro Flies.
After fifteen successful years as an Independent Financial Adviser, Roberts becomes disillusioned with the life insurance industry and becomes a central heating engineer to keep himself occupied between gigs. Roberts and Crowe, with Darren Beale on second lead guitar, and Peter Barton on bass guitar and lead vocals, are now playing together as Boomtown Rats Roberts and Crowe, and are performing material from the Boomtown Rats’ first three albums across Europe and the UK.
