He first became known in the U.K. due to selling Northern Soul 7"s to collectors, both original copies and bootleg copies from his base in Leeds. He also produced versions of Northern Soul tracks, released on his Soul Fox Records and Soul Galore labels. He produced some new tracks which were released under established names without the actual artist's involvement, such as Lorraine Chandler on his Black Magicrecord label. Soussan was involved with the amazing story of how Frank Wilson's "Do I Love You " became the most expensive Northern Soul 7" ever sold. He befriended Tom DePierro at Motown Records, who had discovered one of the only two copies of the single in existence. According to Frank Wilson, the rest were destroyed after Berry Gordy gave him the choice of being an artist or a producer. Soussan borrowed the copy from DePierro and bootlegged it before selling it to Les McCutcheon, future manager of the bandShakatak. The bootleg was slightly sped up and released under the name Eddie Foster, and that version became a Wigan Casino classic. The original copies of the single have since gone on to sell for £15,000 and £25,000.
Re-locating to Los Angeles in the mid-1970s, Simon spent hours on end in many record shops seeking those with the right sound for Northern Soul. One such shop was LoCo Records which was owned by Lonnie Cook. Simon soon learned that Cook was the same person that wrote,,I Thought you were mine,,. That record is now #242 in the top 500 Northern Soul. Simon also assumed Lonnie Cook to be the lead vocalist onArpeggio the Arpeggio album but it was not to be for on the day of the first session Lonnie had laryngitis for the first time in his life. That being so Lonnie sent the first tenor of his reforming Fandangos doo wop group in his stead, his name was Sam Strain. Round about 1973, he turned up on the doorstep of Mirwood Records owner Randy Woods. Woods was in poor health with large medical bills to pay, and Soussan wanted to buy the label. Sources report Woods as opening his garage door and telling Soussan to take what he wanted. Soussan allegedly took everything for an undisclosed sum of money. In the 90's he gave Goldmine/Soul Supply Records exclusive distributors rights to the music. However in the 2010s, Ace Records bought the rights to Mirwood/Mira from Wood's ex business partner and Vee Jay Records owner Betty Chiapetta and currently own the label. Soussan set up a record-exporting business in collaboration with Selectadisc in Nottingham. Soon he began to produce artists during the disco era of the 1980s. He produced Shalamar, Patti Brooks, Santa Esmeralda, Jessica Williams with Arpeggio and the electro group French Kiss, Romance, Charisma, Nicole Stone, Spice of Life, as well as recording with his namesake Simon Orchestra. Soussan scored hits with Jessica Williams "Queen of Fools", and Arpeggio "Love and Desire". While French Kiss had a hit with Panic. He also bought 1960's production company Harthon Productions which leased it's recordings to several major labels, as well as founding Harem Records, devoted to disco music and also to license the 1960's master recordings he now owned, which entered a joint venture in 1985 with Bluebonnet Records and a U.S. distribution agreement with RCA Records.
