Gilbert O'Sullivan (born 1 December 1946) is an Irish singer-songwriter, best known for his early 1970s hits "Alone Again (Naturally)", "Claire" and "Get Down". The music magazine Record Mirror voted him the No. 1 UK male singer of 1972.
Worldwide he has charted 16 top 40 records including six number one songs, the first of which was 1970's "Nothing Rhymed" (for further information see Gilbert O'Sullivan discography). Such was his popularity in the early 1970s that "Matrimony", an airplay and live favourite from his debut album Himself, remains one of his most famous compositions despite never having been a hit single.
His most successful recording period was between 1970 and 1980, though he has since recorded nine studio albums up to 2011's Gilbertville. Speaking in 2009 he said; "I write pop songs. End of story. That's all I wanted to do. That's all I want to do. And that's all I continue to want to do. I have no interest in just touring, and living in the past."
