Sandy Wilson, the author, composer and lyricist whose winsome, nostalgic and tuneful pastiche of 1920s musicals, “The Boy Friend,” made a stage star of Julie Andrews and later a movie star of the model Twiggy, died Aug. 27 in Taunton, England. He was 90.

His agent, Nick Quinn, confirmed the death.

“The Boy Friend,” first staged in 1953, was the grand slam of Wilson’s theatrical career. It ran for more than five years in London and had a respectable run of 485 performances on Broadway with 19-year-old Andrews making her U.S. debut in the lead.

The success of “The Boy Friend” made Wilson the rage of theater circles in London and New York. He was dubbed the next Bright Young Thing.

Achieving fame and riches at 30, he said the rest of his career seemed like a long denouement.
