Elvis Costello consists of Declan Patrick.
Declan Patrick MacManus (born August 25, 1954, in London), better known by his stage name, Elvis Costello, is a popular British musician, singer, and songwriter of Irish ancestry. Some sources list his full given name as Declan Patrick Aloysius MacManus, however Aloysius was not one of his names at birth, being added years later.
Costello was an early participant in London's pub rock scene in the mid-1970s, and later became associated with the punk rock and new wave musical genres, before establishing himself as a unique and original voice in the 1980s. His output has been wildly diverse: One critic has written that "Costello, the pop encyclopedia, can reinvent the past in his own image."
MacManus was born in St Mary's Hospital, Paddington in London, living in the area until he was sixteen. With an already musical family (his father, Ross MacManus, sang with Joe Loss), MacManus moved with his mother to Liverpool in 1971. It was there that he formed his first band, a folk duo called Rusty. After completing secondary school in Liverpool, he moved back to London where he next formed a band called Flip City , which had a style very much in the pub rock vein. They were active from 1974 through early 1976. Around this time, MacManus adapted the stage name D.P. Costello.
By 1975, MacManus was already a husband and father. To support himself, he worked a number of office jobs, most famously at a cosmetics firm -- immortalized in one of his song lyrics as the "vanity factory" -- where he put in time as a data entry clerk. He continued to write songs, and began aggressively looking for a solo recording contract. On the basis of a demo tape, he was signed to Stiff Records. His manager at Stiff, Jake Riviera, suggested a name change, using Elvis Presley's first name and his maternal grandmother's maiden name to form Elvis Costello.
