Rofo consisted of Ronny (ro) Verrept and Fonny (fo) de Wulf from Belgium. Fonny played the instrumental parts, Ronny was more the arranger. Vocals were provided by different vocalists. When their 'Flashlight On A Disconight' was used as the theme song at the Midem '83 in Cannes, Rofo gained worldwide success. Fonny continued Rofo on his own and kept having success with eg. 'You've got to move it on' and 'I want you' (with the very recognisable vocals of John Sauli).
