Brummell's name became associated with style and good looks and was therefore borrowed for a variety of products or alluded to in songs and poetry. One example was the paint colour Beau Brummel Brown, used exclusively on the 1931 Oldsmobile.[38] In 1934 a rhododendron hybridised by Lionel de Rothschild was named after the dandy.[39] In 1928 there were several Beau Brummel styles from the Illinois Watch Company[40] and in 1948 LeCoultre marketed a Beau Brummel watch with a minimalist design and no numbers.[41]
T. S. Eliot's poem about "Bustopher Jones: The Cat About Town" refers to him as the "Brummell of Cats",[42] an allusion taken up in Andrew Lloyd Webber's Cats, the 1981 musical based on Eliot's Old Possum's Book of Practical Cats (1939). Another reference appears in the 1982 musical Annie in the song "You're Never Fully Dressed Without a Smile": "Your clothes may be Beau Brummelly, they stand out a mile."[43]
Other allusions to Brummell appear in the lyrics of such songs as "All I Need Is The Girl" from the 1959 musical Gypsy and Billy Joel's 1980 hit "It's Still Rock and Roll to Me". In the late-1920s, "Zack Whyte and His Chocolate Beau Brummels", a touring ensemble, recorded for Gennett, Champion, and Supertone Records. In addition, name was adopted by rock bands in the 1960s: the faux-British Invasion band The Beau Brummels[44] and Beau Brummell Esquire and His Noble Men, the name used by South African born Michael Bush for his English rock group
