Born in Roubaix, Lefebvre first studied philosophy. He took a few lessons from Pierre Cochereau and following his advice, he went to study at the Conservatoire de Lille with Jeanne Joulain, then at the Conservatoire de Paris where he obtained first prizes in organ, improvisation, fugue and counterpoint.
He began by being organist at Marcq-en-Barœul, then was appointed to the Cathedral of Notre-Dame-et-Saint-Vaast d'Arras in November 1968.

He is a guest at major festivals, as a soloist or with orchestra. He regularly gives concerts and master classes in Europe, the United States, Japan, Russia and Eastern Europe.
In 1985, he was appointed titular organist of the cathedral Notre-Dame de Paris, together with Yves Devernay, Olivier Latry and Jean-Pierre Leguay. He succeeds his master Pierre Cochereau.
A talented interpreter, he is also recognised as one of the greatest improvisers of his time.
