When Leslie Kong died from a heart attack in 1971, Lyn became Toots & The Maytals' manager and is credited as co-producer for two of the group's well-known albums, 1973's Funky Kingston and Reggae Got Soul, which was released three years later.
For most of the 1970's, Lyn worked with Tommy Cowan at Talent Corporation. They managed and produced acts like Melodians, Ras Michael & The Sons Of Negus, Zap Pow, Inner Circle and Junior Tucker.
Lyn immigrated to the United States in the early 1980's where he operated a painting business. He and his wife, 1973 Miss Jamaica, Patsy Yuen, also ran the Miss Jamaica Miami beauty pageant.
