Il Etait Une Fois (Once Upon a Time) were a band—like The New Seekers and The Carpenters—whose music combined the carefree nature of the early '70s with an underlying poignancy. Arrangements of some of their best-known tracks were born in the dreamy world of the music hall, lifting away worries with happy harmonies and the feather-light vocals of Joëlle Mogensen. Rounded out with brass sections, strings and disco-beat synths, these timeless songs elegantly recall that bygone age.
