In the late 60s arranger, conductor and multi-instrumentalist Hewson worked with James Taylor and Herbie Hancock and arranged hits such as the Beatles "The Long And Winding Road" and Mary Hopkins' "Those Were The Days." His fame as an arranger spread and in the next decade he worked with artists including Supertramp, Diana Ross, Carly Simon, Art Garfunkel, Leo Sayer, Chris Rea to name a few.
In 1976 he decided to produce, write and play on his own records under the name RAH Band. In 1977 the instrumental "The Crunch" on Good Earth climbed into the UK Top 10. Three years later "Falcon" hit the Top 40 and started a long string of dance hits for the band. In 1985 "Clouds Across The Moon," with vocals by his wife Liz, gave him a second Top 10 single. Over the years the band have chalked up seven UK hits and have had records on a myriad of labels including DJM, KR, TMT, Sound, RCA, Supreme and Creole.
Hewson, who in the 80s worked with Toyah and Five Star and produced big hits for Cliff Richard and Shakin' Stevens, now concentrates on writing and producing music for UK television shows and advertisements.
