Flynn portrayed Corporal Paddy Garvey of the King's Fusiliers in the ITV series "Soldier Soldier". The series began in 1991. He acted alongside Robson Green in the series. After Flynn and Green performed "Unchained Melody" on the programme, ITV was inundated by people looking to buy the song, and the pair were persuaded by record producer Simon Cowell to record it and release it as a single, a double A-side with White Cliffs of Dover. The single was released under the name Robson & Jerome and reached number one in the UK chart in 1995. It stayed at No.1 for 7 weeks in the UK Singles Chart, selling more than 1.9 million copies and making it the best-selling single of the year, and winning the duo the Music Week Awards in 1996 for best single and best album. The duo had two more number one hits in 1995 and 1996 with "I Believe" and "What Becomes of the Brokenhearted" both re-makes of standards, they also produced two number one albums.
