“Itsy Bitsy Teenie Weenie Yellow Polkadot Bikini” dominated AM radio in 196o, making Brian Hyland a teen idol in the process. The song hit No. 1 on the Billboard Hot 100 and was a hit around the world. It was written by Paul Vance and Lee Pockriss and first released in June 1960, inspired by Vance’s daughter, who was too shy to wear a bikini in public.
