 The composition first came to the attention of Americans in 1979, when it was featured in the hit film Ten, starring Dudley Moore and Bo Derek. The court ruled Friday that French composer Maurice Ravel wrote Bolero by himself in 1928. The ruling deals a financial blow both to Ravel's descendants and to those of Russian stage designer Alexander Benoit, who said he helped create it. In a statement, the court said the ruling means the composition remains in the public domain.
