That year they began touring throughout Europe as a live performance band, singing songs in English of their favorite artists, such as Little Richard, Chuck Berry, Elvis Presley and The Rolling Stones.

In 1972, Alain Tobably formed a partnership with Doug Yeager and Charles Benanty of Applewood Productions in New York, and the band began the second phase of their career touring and recording in America.

In 1974, Les Variations became the first French rock band to sign with an American label, Buddah Records, while creating a more exotic and unique style reminiscent of their North African roots.

In the summer of 1975, after the band's national tour of America in support of their charted album, Robert Fitoussi choose to branch out on his solo career as F. R. David.

Les Variations reformed at their Cincinnati band house and studio with Tobaly, Bitton and Morris and the addition of American singer Carl Storie and bassist/singer Albritton McClain.

Jac Hammer, composer of many classic rock songs such as "Great Balls of Fire," wrote an anthem the night Anwar Sadat flew to Israel to make peace.

Three days later, Richie Havens and Les Variations recorded "Shalom, Salem Aleicum" (produced by Charles Benanty, Doug Yeager and David Wilkes), which CBS released immediately throughout the Middle East, and it became a #1 hit in Israel, Egypt and Jordan.

Over their ten years on the road they toured with many major acts of the era, including: Bachman–Turner Overdrive, Kiss, The Jimi Hendrix Experience, Cream, Yes, Guess Who, Taste, Queen, Uriah Heep, Rush, Kraftwerk and Aerosmith, to name a few.
