"Cathy's Clown" was released in April 1960 and became the biggest hit of the legendary American country-influenced Rock'n Roll duo. The lyrics describe a man who has been wronged and publicly humiliated by his lover: 'here he comes, that's Cathy's clown'. The choruses are sung by brothers Don and Phil in their trademark close harmony style, while Don síngs the bridges solo. "Cathy's Clown" is noted for its unorthodox structure, such as beginning on a chorus and having bridges but no verses. The song spent five weeks at no.1 on the US Billboard Hot 100 and seven weeks at the summit on the UK Singles Chart.
