Gaines was born and brought up in the Borough Park section of Brooklyn, New York and attended Erasmus Hall High School and New York University, where he studied with film director Martin Scorsese.His father was a school teacher and child guidance counselor, and his mother a bookeeper.He graduated near the bottom of his class at Erasmus Hall, and flunked out of Temple University, in Philadelphia, Pennsylvania. It was in Philadelphia that he met children's TV star Gene London who first encouraged him to write.

Gaines was working in a small auction gallery in 1971 when he met former child evangelist Marjoe Gortner at Max's Kansas City, a New York restaurant and club. Although Gaines had never published anything before he convinced Gortner to allow him to write his biography, which was published by Harper & Row (now HarperCollins) in 1973.The movie of "Marjoe" won the 1972 Academy Award for Best Documentary, and although the film was not based on Gaines' biography, the attention brought by the Academy Award helped promote the book "Marjoe" into a religion bestseller and establish Gaines' career as a writer.

The same year Marjoe was published, Gaines became editor of Circus, a national teeny-bopper rock and roll magazine, and he also began a six-year run as the "Top of the Pop" columnist for the New York Sunday News, on alternate Sundays, dual positions that gave him a catbird seat in the fast lane of the rock and roll business during the golden era of the seventies.

Gaines spent a year on the road living with Alice Cooper, and in 1976 he published "Me, Alice," by Alice Cooper with Steven Gaines, the first autobiography of a rock star. Published only in hardcover, the book has since become a collectors' item and sells for up to $2500 a copy.

In 1980 Gaines met Robert Jon Cohen, a 21 year-old Studio 54 bartender, with whom he collaborated on a book called The Club, a thinly-veiled roman a clef about Studio 54. The book a raised the ire of nightclub owner Steve Rubell, designer Halston, and singer Liza Minelli, among others. Fodder for the gossip columns, the book caused a sensation and got advances in the six-figures, but won Gaines ignominy. Soon after the publication of The Club, Gaines moved to Laguna Beach, California, then to London, and finally to East Hampton, New York, where he wrote the international best-seller The Love You Make: An Insiders Story of the Beatles, with Beatle insider Peter Brown. Published in 1983, The Love You Make was on the New York Times Hardcover bestseller list for 16 weeks.

Gaines began his journalism career as the "Top of the Pop" columnist for the New York Daily News [9]. In the early part of his career he wrote several books about the music business, including Alice Cooper's autobiography, "Me, Alice"; "The Love You Make," a biography of the Beatles; and "Heroes and Villains," a biography of the Beach Boys, before briefly switching his focus to fashion designers with biographies on Halston and Calvin Klein.

In 1980 he published a controversial "roman a clef" called The Club about the nightclub Studio 54 that he co-wrote with a 21 year-old Studio 54 bartender, Robert Jon Cohen. As Robert Granit, he published "Another Runner in the Night" in 1981, a novel about a homosexual film producer married to the daughter of a studio boss. He is credited with coining the phrase "velvet mafia" in reference to the influential gay crowd who ran Hollywood and the fashion industry.

Gaines is best known for his 1998 social and cultural history of the East End of Long Island called Philistines at the Hedgerow: Passion and Property in the Hamptons.

In 1993 he co-founded the Hamptons International Film Festival.
