SIR Bob Geldof has been sued by his former Boomtown Rats bandmates for allegedly refusing to share the group's fortune since they split. Guitarist GARRICK ROBERTS, who now has a plumbing job to pay the bills, insists he "hasn't received a penny" in royalties from hits including I DON'T LIKE MONDAYS and RAT TRAP since 1986. He's reunited with former band members JOHN MOYLETT, GERRY COTT and SIMON CROWE to issue a joint legal statement demanding compensation from Geldof. He says of the crusading star, "He was always much more of a self publicist than the rest of us. He's learned to use his fame. It's what he's about now."
