Q:What is the last name of the person who formed the band named Jaojoby?  Answer the above question based on the context below:  After several years having focused entirely on his career with the Regional Information Service, Jaojoby was approached in 1987 by Frenchman Pierre Henri Donat to contribute several recordings to Madagascar's first salegy compilation album, Les Grands Maîtres du Salegy ("Grand Masters of Salegy"). The runaway success of one of the tracks he composed and performed, "Samy Mandeha Samy Mitady", elevated salegy from a regional genre to one of nationwide popularity, leading a newspaper to declare him the "King of Salegy". High demand for live performances led the singer to return to Antananarivo in 1988 to form a band named "Jaojoby" that included former bandmates from Los Matadores and The Players. Jaojoby begin touring regularly at home and abroad, performing his first international concerts in Paris in 1989. In the meantime, he worked as a press attaché for the Ministry of Transport, Meteorology and Tourism from 1990 until 1993, at which point he left his job to become a full-time musician.The 1992 release of Jaojoby's first full-length album, titled Salegy!, was facilitated by fRoots magazine editor Ian Anderson, who had worked with Jaojoby to record several of his tracks for a radio broadcast two years previously. Jaojoby's second album, Velono, was the first salegy album to be recorded in France, as well as the first of his albums to be produced in a professional-quality recording studio. Following the 1994 release of Velono, Jaojoby became a regular on the international music festival circuit and has performed at such events as WOMAD in Reading, the Festival du Bout du Monde in Brittany, WOMEX in Spain, the Festival des Musiques Métisses in Angoulême, the MASA Festival in Abidjan, and similar events in Germany, the Netherlands, and Portugal. Jaojoby's excitement over his rise to international celebrity was attenuated by the 1995 death of the band's original drummer, Jean-Claude Djaonarana, who had first performed with Jaojoby as a member of Los Matadores.
