The Harvard Din & Tonics, informally known as the Dins, are a self-directed, five-part jazz a cappella group from Harvard University in Cambridge, Massachusetts, founded in April 1979. Originating as a public service project of the Phillips Brooks House Association, the ensemble initially drew its repertoire from the Dunster Dunces and made its public debut at Yale University in November 1979. Comprising twelve to fifteen undergraduate students, the group is celebrated for performing in white tie, tails, and signature lime green socks, reflecting their slogan, “A cappella with a twist”. The Dins made their feature film debut in First Affair (1982) and subsequently appeared in the 2003 movie Mona Lisa Smile. Since 1983, the group has produced nineteen albums, including In the Beginning, Sublime, The Dark Side of the Lime, and Zest. Their signature track, “Sh-Boom”, has been featured on fourteen of their first fifteen albums. Since 1990, the group has embarked on biennial world tours across Europe, Africa, Asia, Australia, North America, and South America, performing for figures such as Ella Fitzgerald, Wynton Marsalis, and Bill Clinton. Notably, they performed an original medley for composer John Williams at Harvard's 366th Commencement. Historically an all-male group, they admitted their first female member in 2018, a second in 2019, and have also featured their first transgender member, Elio Kennedy Yoon.
