Gilbert O'Sullivan is an Irish singer-songwriter. He has had six number one singles worldwide. He reached global stardom with his 1972 hit "Alone Again (Naturally)", which reached No. 3 in the UK; No. 1 in the US, and spent six weeks at No. 1 on the billboard Hot 100 Chart, selling nearly 2 million copies. For the next 5 years, he enjoyed huge worldwide success, but his relationship with his record label soured, and this led to a dramatic downturn in his output - between the years of 1982 and 1987 he didn't release any new material at all. However, he now releases new material, and continues to perform around the world.
