The multi talented Hart is known as an industrious figure on the British Rock scene having fulfilled roles as producer, singer, songwriter, manager and British music ambassador internationally. Originally a member of THE ROLL UPS who had released a single, 'Blackmail', on the Bridgehouse label in 1979 and an album entitled 'Low Dives For High Balls' the same year. Vocalist Lea Hart supported JUDAS PRIEST on their 1979 'Killing Machine' British tour with the group that boasted a line-up of bassist Jeff Peters, drummer Rick Andreo and keyboard player Paul Airey. An album was recorded, but this was never released and Lea then formed the LEA HART BAND which evolved into YA YA. Hart quit YA YA prior to their second album.
The man joined FASTWAY as vocalist, replacing Dave King, and released two albums with the band. Whilst a member of FASTWAY, Lea busied himself on promoting British bands in the former Soviet Union. Indeed, he also produced the London based FIRST STRIKE's demo in 1989 to boot. Further afield Hart would lend his vocal talents sessioning on Japanese act AIR PAVILION's 'Kaizoku' album.
