Lee (Vassilis) Simon was born in 1954 in Melbourne to Greek
immigrant parents. At age five, he changed his first name to Lee, as "it
was easier to use." He worked as an audio engineer from 1971 at local
radio station, 3AW. His first job as a DJ was for radio 2BE in Bega, New South
Wales followed by stints at 7HT (Hobart), 2NX (Newcastle) and 2SM (Sydney).


Simon returned to Melbourne as a DJ and announcer for radio
station 3XY (from 1975) and then EON FM (from 1980), where he became their programme director. He hosted Nightmoves, claimed as Australia's first adult and album-orientated music TV program for HSV 7, from 13 May 1977.


Initially trialled for six weeks it was subsequently transmitted nationally via the Seven Network for late Friday night programming from about midnight to 1:00 a.m. By 1982 it was being broadcast on Network 10 at about 10:30 p.m. Monday nights. In 1985 it was re-branded as Rockit for the Nine Network.


 In 1995 Simon, as Program Director, was instrumental in
Triple M Melbourne (formerly EON FM) beginning live radio broadcasts of AFL matches. As from 2010 he presented the retro music programme, Rock of Ages on Triple M. In 2018 he retired and was inducted into the Australian Commercial Radio Awards Hall of Fame later that year.
