Who were the first act in UK chart history to have their first three singles go straight in at number one?

Robson & Jerome are an English pop duo who were active in the mid-1990s, consisting of actors Robson Green and Jerome Flynn. They rose to prominence via the English television series "Soldier Soldier".

In November 1994, in an episode of the UK television drama series "Soldier Soldier", actors Robson Green and Jerome Flynn performed "Unchained Melody" as an impromptu duo The Unrighteous Brothers after the entertainment failed to appear at a wedding. Their performance triggered a big response from the audience and ITV was inundated by people looking to buy the song. Simon Cowell was alerted to the interest shown by the public, and pursued the two reluctant actors. The actors were eventually persuaded to sign a recording contract with Cowell and record a Righteous Brothers-type version of the song as a duo.

Their cover of "Unchained Melody" was released and it immediately reached No. 1 and stayed there for seven weeks, and became the best-selling song of 1995 in the UK. It was also the best-selling song of the 1990s, until it was over-taken by "Candle in the Wind 1997", Elton John's tribute to Diana, Princess of Wales. It remains one of the country's best-selling singles. Their two follow-up singles, "I Believe" released later in the year, and "What Becomes of the Brokenhearted" released in 1996, also reached No. 1 on their release, and they became the first act in UK chart history to have their first three singles go straight in at number one.
