Throughout the 1990s, Demers recorded jingles for many high-profile clients, including Chevrolet, AOL, McDonald's and the groundbreaking worldwide campaign of "Always Coca-Cola".

He was a member of an R&B/pop group, Truth Inc. Demers has traveled widely, singing in, among other venues, Shanghai, where he performed at the closing ceremonies for the Special Olympics World Summer Games, and Versailles.

Demers has worked with music industry figures Diane Warren, David Foster, Giorgio Moroder and Tim Rice.

His brother Donnie Demers wrote the words and music to several of the songs, including "It's A Lonely World" (which was featured on the Sirius radio show of author Deepak Chopra.)

A&M Record's co-founder Herb Alpert, Billie Dee Williams and model Cheryl Tiegs were among those who joined Abdul as Jimmy and Donnie performed to a capacity audience.
