C / G / A flat / E flat … Any French traveler hearing these instantly-recognizable four notes would know to listen up and pay attention, as the official jingle for the country's SNCF railway company typically precedes announcements of trains leaving or arriving, platform changes, and all too often ... delays.

But back in 2013, when David Gilmour — the legendary singer and guitarist of Pink Floyd fame — heard the audio alert in the train station of the southern French city of Aix-en-Provence, he wanted to take it home. As local daily Ouest France recalls, the British songwriter promptly got his phone out to record the tune; later on, he tracked down the jingle's composer, French sound designer Michaël Boumendil, to discuss the sampling of the jingle in a future song.

At the time, Boumendil told French radio station RTL of his surprise at receiving a phone call from Gilmour, who introduced himself by saying, "I'm a guitarist, from the band Pink Floyd..."

Arrangements were made, a contract was signed: The Frenchman would be listed as co-author of the song and get a 12.5% cut of revenue generated. Meanwhile, the SNCF also gave its thumbs up — and in 2015 Gilmour released his fourth solo album, Rattle That Lock, whose title song incorporated the catchy SNCF riff.

But then, the story began to turn sour. Shortly before the song hit the airwaves, Boumendil gave several interviews, boasting about the prestigious collaboration. This, according to the musician"s team, was a breach of a confidentiality clause, as the song had not yet come out — so much so that they decided to exclude the sound designer from the promotion campaign of the album.

Things escalated quickly, Boumendil sued Gilmour on plagiarism grounds, a claim that was rejected by a Paris court in 2019. Boumnedil appealed, again to no avail — and the legal battle ran its full course last week, as French economics and business magazine Capital reports, with the Paris Court of Appeal condemning the Frenchman to pay 10,000 euros in legal fees. And since it's not all about the Money, Gilmour was also granted the right to keep using the four-note jingle.
