"Rock Bottom," which he wrote in partnership with Lynsey de Paul, was the UK entry in the Eurovision Song Contest 1977 and put him in the spotlight for the first time. Although leading early on in the voting, the song eventually came second in the Contest. Nevertheless, it went on to become a top 20 hit in many European countries including France, Germany, Austria and Switzerland where it reached the top of the singles charts. It was more successful in Continental Europe than in its country of origin, the United Kingdom.
De Paul and Moran went on to write a number of songs such as "Let Your Body Go Downtown", a top 40 hit for the Martyn Ford Orchestra and the follow up "Going to a Disco" as well as "Without You" and "Now and Then" which appeared on the albums "Tigers and Fireflies" and "Just a Little Time", respectively.
For many years, Moran was the Musical Director for the UK ITV children's music show "Get It Together", performing on the show each week, accompanying the various studio guests and playing the show's theme tune. He had another stab at writing a UK Eurovision entry in 1990, when he wrote "That Old Feeling Again" for Stephen Lee Garden, which placed 5th out of the 8 songs in the competition.
Latterly, Moran has worked extensively as a music producer. He produced The Queen Album and Piaf for Elaine Paige and has just completed her latest album Essential Musicals.
