"Sunday Girl" was released in the UK as a fourth single from the album in May 1979 and also reached no.1, and ''Parallel Lines'' became the UK's biggest selling album of the year. Blondie embarked on a sold-out tour of the UK and appeared at an autograph signing event for [[Our Price Records]] on [[Kensington High Street]]; according to Peacock, it "descended into [[Beatlemania]]-esque chaos when the band were mobbed by thousands of fans".<ref name="udiscover"/>

''Parallel Lines'' was also a commercial success elsewhere in Europe, Australia, and the United States, where the band had struggled to sell their previous records. "Heart of Glass" became their first number-one hit on the American [[Billboard Hot 100|''Billboard'' Hot 100]], with help from a promotional video directed by [[Stanley Dorfman]] depicting Blondie in a performance of the song at a fashionable nightclub in New York. The single was "responsible for turning the band into bona fide superstars", Peacock said.
