Alone Again (Naturally)

"Alone Again (Naturally)" is a song by Irish singer-songwriter Gilbert O'Sullivan. Recorded in 1971, it became a worldwide hit. The song did not originally appear on his 1972 studio album Back to Front, but has been included in reissues (often replacing "Clair").

The single spent six non-consecutive weeks at number one on Billboard's Hot 100 between late July and early September 1972 in America. It ranked number two in the year-end chart and sold over two million copies.

The song was involved in a notable 1991 court case in which it set a precedent for the music industry that unauthorized sampling of music can constitute copyright infringement.
