Apart from his father, March-Tormé's early musical influences include The Four Seasons, Nat King Cole, The Temptations, Ricky Nelson, and Gene Pitney.

In 1956, Candy Toxton married actor/comedian Hal March, who was the host of The $64,000 Question game show, and starred in Neil Simon's Come Blow Your Horn on Broadway.

After games he would turn to Top 40 music stations and sing with The Four Seasons, Nat King Cole, The Temptations, Ricky Nelson, Gene Pitney, and The Beatles.

[1] After March and Toxton moved to Beverly Hills, California, March-Tormé formed friendships with Desi Arnaz Jr., Dean Martin Jr., Miguel Ferrer, Carrie Fisher, and Liza Minnelli while attending high school.

During this time, he continued to develop as a musician and his influences grew to include Joni Mitchell, James Taylor, Todd Rundgren and Steely Dan, all of whom March-Tormé pays homage to on his 2009 album Inside/Out.

The album included Arthur Adams, Wilton Felder and Wayne Henderson of the Jazz Crusaders, Fred Tackett and Paul Barrere of Little Feat, Jimmy Gordon from Derek and the Dominos, Max Bennett, Chuck Findley, Victor Feldman, Plas Johnson, and Pete Christlieb.

[2] His audition consisted of singing Elton John's "Daniel" and Stevie Wonder's "My Cherie Amour" for the producers, who hired March-Tormé the next day.

When told that recommendation had come from Quincy Jones (who had seen March-Tormé perform at a tribute show to Henry Mancini at the Hollywood Bowl) and that the album would be produced by Richard Perry, March-Tormé went to the offices of Planet Records to sing "Serenade in Blue" and "Blue Suede Shoes" for Richard and his partner, movie producer Joel Silver.

Full Swing included Paulinho Da Costa, Paul Jackson Jr., Victor Feldman, Chuck Findley, Gary Grant, Dick "Slide" Hyde, Tom Scott, David Benoit, Jerry Hey, Conte Candoli, Lew McCreary, Richard Tee, Vinnie Colaiuta, and Russ Kunkel.

Four musicians from this recording (Gary Herbig, Ira Newborn, Joel Peskin, and Pete Christlieb) would later work with March-Tormé on his solo albums.

In 2000 he performed at Feinstein's in New York City, the Dakota Jazz Club in Minneapolis, and the Hollywood Bowl, where he paid tribute to his father.
